Since PERF_FORMAT_LOST was added, the default read format has that bit
set, so add it to the tests. Keep the old value as well so that the test
still passes on older kernels.
This fixes the following failure:
expected read_format=0|4, got 20
FAILED './tests/attr/test-record-C0' - match failure
Fixes: 85b425f31c8866e0 ("perf record: Set PERF_FORMAT_LOST by default")

d0d1dd628527c77d ("perf core: Add PERF_COUNT_SW_CGROUP_SWITCHES event")
Also change the expected sizeof(struct perf_event_attr) from 120 to 128 due to
fields being added for the SIGTRAP changes.
Addressing this perf build warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/perf_event.h' differs from latest version at 'include/uapi/linux/perf_event.h'

During the processing of /proc during event synthesis new processes may
start. Add a dummy event if /proc is to be processed, to capture mmaps
for starting processes. This reuses the existing logic for
initial-delay.
v3 fixes the attr test of test-record-C0
v2 fixes the dummy event configuration and a branch stack issue.
