kmsan: introduce test_unpoison_memory()
Add a regression test to ensure that kmsan_unpoison_memory() works the
same as an unpoisoning operation added by the instrumentation.
The test has two subtests: one that checks the instrumentation, and one
that checks kmsan_unpoison_memory(). Each subtest initializes the first
byte of a 4-byte buffer, then checks that the other 3 bytes are
uninitialized.
[glider@google.com: change description, remove comment about failing test case]
