perl: link to the system zlib instead of a vendored copy

The perl module Compress-Raw-Zlib defaults to using a vendored copy of
the zlib sources which has a number of CVEs.  A newer version of perl
updates this to zlib 1.3.2 to resolve them, but we should be linking to
our zlib recipe instead of the vendored code.

This mitigates CVE-2026-4176 so mark it as not appropriate.
