Current test expects test_lower to fail with: truncate(test_lower) should have failed While it is sort of okay to fail like that (the above expectation basically acknowledges this weirdness in the overlayfs implementation), it is by no means the only correct behavior: it is also correct for the test to succeed (i.e. truncation fails with ETXTBSY). So add an option to t_truncate_self.c that allows both success and failure, but obviously not SIGSEGV, which is what a we'd get in a real failure mode.

# Test truncate running executable binaries from lower and upper dirs.

# truncate(2) should return ETXTBSY, not other errno nor segfault

# Commit 03bea6040932 ("ovl: get_write_access() in truncate") fixed this issue.
