Julien Olivain 8dea6e7c08 package/perl: apply perl-cross patch only on target perl
Buildroot commit [1] (package/perl: fix build issue with musl)
introduced a patch that is meant to be applied on top of perl-cross,
which is extracted on top of perl only in the target variant.

Since the patch was introduced as a normal package patch, the Buildroot
infra is trying to always apply it, even for the host package variant.
Since perl-cross is not extracted for the host variant, some patched
files are missing. In that case, the host-perl is failing with error:

    >>> host-perl 5.42.3 Patching
    Applying 0001-configure-keep-_GNU_SOURCE-in-build-flags.patch using patch:
    can't find file to patch at input line 46

This commit fixes the issue by moving the package patch in a dedicated
"perl-cross" subdirectory, to make sure it will no longer be applied by
the infra. We apply the patch only for the target package variant using
a _POST_PATCH_HOOKS hook.

Fixes:
- [1]
- https://gitlab.com/buildroot.org/buildroot/-/jobs/16185948610 (TestPerlXMLLibXML)
- ...and few other tests requiring host-perl
