Metadata restore failures still return ARCHIVE_WARN, because that's non-critical. Fix test_write_disk_secure test to verify the correct return code in one case; add test_write_disk_failures to do another very simple test of restore failure. This should fix cpio coredumping when it tries to restore to a write-protected directory.
