gnu: emacs-emms-print-metadata: Fix build.

This package is failing to build, with:

    ld: cannot find -lz: No such file or directory

...because `taglib-config --cflags --libs' is included in the gcc arguments,
and includes "-lz".  Since zlib isn’t in the inputs, it can’t be found, and
the build fails.  Adding it to the package inputs allows the build to succeed.

Re #5592.

* gnu/packages/emacs-xyz.scm (emacs-emms-print-metadata): Add zlib to inputs.

module cycle.  Remove it.
