Use Sub::Override for Archive::Zip workarounds instead of Monkey::Patch (see #8

 for more information). (Closes: #931730)

Monkey::Patch recursively depends on an XS binary Perl module which creates
build cycle issues for Perl transitions.

Use Sub::Override instead as it has no dependencies outside Perl core.
