make zlib-related modules a hard dependency

This allows us to simplify some of our existing code and make
future changes easier.

I doubt anybody goes through the trouble to have a Perl
installation without zlib support.  The zlib source code is even
bundled with Perl since 5.9.3 for systems without existing zlib
development headers and libraries.

Of course, zlib is also a requirement of git, too; and we're not
going to stop using git :)
