perf test: Test 73 Sig_trap fails on s390
In Linux next commit 5504f67944484495 ("perf test sigtrap: Add basic
stress test for sigtrap handling") introduced the new test which uses
breakpoint events. These events are not supported on s390 and PowerPC
and always fail:
# perf test -F 73
73: Sigtrap : FAILED!
#
Fix it the same way as in the breakpoint tests in file
tests/bp_account.c where these type of tests are skipped on s390 and
PowerPC platforms.
With this patch skip this test on both platforms.
Output after:
# perf test -F 73
73: Sigtrap
#
Fixes: 5504f67944484495 ("perf test sigtrap: Add basic stress test for sigtrap handling")
