Reland "libbinder: ignore CallRestriction for magic 0 cmd"

This reverts commit 41a4c36712b23aff58d9305e4191dc18d143f6bd.

This fixes the CallRestriction issue, but removes the added test
which has problems in another context and will be fixed separately.

Reason for revert: refix b/167302413
Testing issue will be handled separately in b/168942807.

Fixes: 167302413
