Revert "d2: don't build without proprietary blobs"

This breaks the official build instructions from the wiki, which have
you breakfast and then extract the proprietary files from your device
before building (as opposed to already having them synced from somewhere
else)

Repository synced!
Looking for dependencies
Done
build/core/product_config.mk:238: ***

common/d2-common-vendor.mk" does not exist.  Stop.

** Don't have a product spec for: 'cm_apexqtmo'
** Do you have the right repo manifest?
