build: Do not check if system perl modules should be bundled

build: Do not check if system perl modules should be bundled

We do not ship any perl modules in third_party at this time, so
this check is pointless and breaks the build for --bundled-libraries=ALL.

As reported by aaptel on https://gitlab.com/samba-team/samba/-/merge_requests/1104#note_281050331

This changes our autobuild script to cover this case in the
samba-static job.
