Fix seccomp relocatable builds. This is a simple fix to use the
right lib.mk variable TEST_GEN_PROGS. Local header dependency
is addressed in a change to lib.mk as a framework change that
enforces the dependency without requiring changes to individual
tests.
The following use-cases work with this change:
In seccomp directory:
make all and make clean
From top level from main Makefile:
make kselftest-install O=objdir ARCH=arm64 HOSTCC=gcc \
CROSS_COMPILE=aarch64-linux-gnu- TARGETS=seccomp

When a selftest would timeout before, the program would just fall over
and no accounting of failures would be reported (i.e. it would result in
an incomplete TAP report). Instead, add an explicit SIGALRM handler to
cleanly catch and report the timeout.
Before:
[==========] Running 2 tests from 2 test cases.
[ RUN ] timeout.finish
[ OK ] timeout.finish
[ RUN ] timeout.too_long
Alarm clock
After:
[==========] Running 2 tests from 2 test cases.
[ RUN ] timeout.finish
[ OK ] timeout.finish
[ RUN ] timeout.too_long
timeout.too_long: Test terminated by timeout
[ FAIL ] timeout.too_long
[==========] 1 / 2 tests passed.
[ FAILED ]

In order to better handle timeout failures, rearrange the child waiting
logic into a separate function. This is mostly a copy/paste with an
indentation change. To handle pid tracking, a new field is added for
the child pid. Also move the alarm() pairing into the function.

ionmap_test compile rule is missing ipcsocket.c dependency. Add it to
fix the following compile errors:
..android/ion/ionutils.c:221: undefined reference to `sendtosocket'
..android/ion/ionutils.c:243: undefined reference to `receivefromsocket'

make kselftest-all O=objdir builds create generated objects in objdir.
This clutters the top level directory with kselftest objects. Fix it
to create sub-directory under objdir for kselftest objects.

The seccomp selftest reported the wrong test counts since it was using
slightly the wrong API for defining text fixtures. Adjust the API usage.

For now, disable MBA and MBM tests for AMD. Deciding test pass/fail
is not clear right now. We can enable when we have some clarity.

Cache Allocation Technology (CAT) selftest allocates a portion of
last level cache and starts a benchmark to read each cache
line in this portion of cache. Measure the cache misses in perf and
the misses should be equal to the number of cache lines in this
portion of cache.
We don't use CQM to calculate cache usage because some CAT enabled
platforms don't have CQM.

Cache QoS Monitoring (CQM) selftest starts stressful cache benchmark
with specified size of memory to access the cache. Last Level cache
occupancy reported by CQM should be close to the size of the memory.

MBA (Memory Bandwidth Allocation) test starts a stressful memory
bandwidth benchmark and allocates memory bandwidth from 100% down
to 10% for the benchmark process. For each allocation, compare
perf IMC counter and mbm total bytes from resctrl. The difference
between the two values should be within a threshold to pass the test.
Default benchmark is built-in fill_buf. But users can specify their
own benchmark by option "-b".
We can add memory bandwidth allocation for multiple processes in the
future.

MBM (Memory Bandwidth Monitoring) test is the first implemented selftest.
It starts a stressful memory bandwidth benchmark and assigns the
bandwidth pid in a resctrl monitoring group. Read and compare perf IMC
counter and MBM total bytes for the benchmark. The numbers should be
close enough to pass the test.
Default benchmark is built-in fill_buf. But users can specify their
own benchmark by option "-b".
We can add memory bandwidth monitoring for multiple processes in the
future.
