perl: link to the system bzip2 instead of a vendored copy

The perl module Compress-Raw-Bzip2 defaults to using a vendored copy of
the bzip2 sources. We should be building perl against the system bzip2
recipe to avoid potential security issues.

This is a little fiddly in the DEPENDS as bzip2-native is assume-provided
so we need to depend on bzip2-replacement-native for the native build.
