No access to tee domain over Unix domain sockets

The tee domain is a vendor domain. Thus it cannot be accessed by
non-vendor components over Unix domain sockets.

It appears that the rules granting this access are not needed.

Test: Flash a clean build with this change. Confirm that bullhead,
      angler, sailfish, ryu, boot without new denials.
      Confirm that YouTube, Netflix, Google Play Movies play back
      videos without new denials.
