AAPT: Don't imply specific location hardware for dump badging

Permissions such as android.permission.ACCESS_FINE_LOCATION
and android.permission.ACCESS_COARSE_LOCATION assumed the underlying feature
technology and aapt dump badging would emit an implied feature.

This is no longer accurate, so the only implied feature is on the general
android.hardware.location when the target SDK of the app is 21+.
