Prefer a simple return; for cases where the target libc doesn't have the API being tested. I know we haven't historically been consistent about this elsewhere, but when porting the libc tests to test/c/, I tried to make sure that error.SkipZigTest is only used for unexpected failures.

historically this is why many test runners differentiate between Skip and Todo.
Todo means it should work but does not.
Skip means it's not applicable.
