remove product/etc/CarrierSettings/ from dep_files

Inline carrier settings extraction is no longer used.

This directory is not filtered out elsewhere, it will still be included in full (non-prep) vendor
modules. However, collected system state files that were generated prior to this commit need to be
regenerated, since they list these files as included in AOSP due to the way dep_files directive
works.
