selftests/mm: unify pkey sighandler selftest assertions and tracing

Browse source

Add per-test tracing to the pkey signal-handler selftest and use
pkey_assert() for error handling.  Each test enables tracing at start and
disables it at end; on failure, pkey_assert() calls abort_hooks() to turn
tracing off so ftrace is not left enabled.
