Subject: [PATCH v3 5/9] selftests/arm64: Fix build warnings for ptrace

"%s" should have been used in ksft_exit_fail_msg(). Anyways, replace that
with the recently introduced ksft_exit_fail_perror(). Also fix no mention of
type_name in ksft_test_result_skip().

NOTE: This patch can be applied independently of the series, but the
next patch depends on this one.

Fixes: ecaf4d3f734f ("kselftest/arm64: Add test coverage for NT_ARM_TLS")
Fixes: cb5aa6379438 ("kselftest/arm64: Add a smoke test for ptracing hardware break/watch points")
Signed-off-by: Dev Jain <dev.jain@....com>
