Set location provider state on group level

Change the location provider and extra location package's location grant
state on the package level, not the individual permission level. This
prevents packages being incorrectly marked as user sensitive.

Test: Go to the location permissions screen, on a device with google
play services as its location provider. Google play services should not
be shown unless you select "show system"
