Implement vendor as a synonym of proprietary

The vendor image will have more than just proprietary modules in it
under Treble, so let's stop marking open source code as proprietary just

Bug: 36452052
Bug: 37134596
Test: compare build.ninja before/after, no changes.
Test: Set vendor: true, ensure it works.
