Mac: Build legacy Quicklook plugin w/o CLD2

Don't include language detection in PoeditQuicklook.qlgenerator.

This was originally done for the modern QuicklookPreview.appex
replacement only accidentally, but it makes sense to do it:
language detection is much less useful in the context of merely
previewing files, and removing CLD2 halves binary size of these
extensions.
