Subject: [PATCH v1 1/2] Revert "selftests: kselftest_harness: fix compile warnings"

This reverts commit f3380b7b8a72f435daceb49f7f7513f3ea2ce5ea.

The OPTIONAL_HANDLER macro, called by all ASSERT_* and EXPECT_* macros,
must support an optional error handler. This is done with an optional
block after the "for" loop.

This enable to pass 52/52 seccomp-bpf tests instead of 42/52.
