cpio.pm: add --verbose statement when Archive::Cpio is missing
When Archive::Cpio is missing, strip-nondeterminism does nothing while looking like it does - especially in verbose mode. This commit fixes -v output from:
strip-nondeterminism -v some.cpio Normalizing some.cpio
to:
strip-nondeterminism -v some.cpio Normalizing some.cpio Archive::Cpio not found
