location: Replace ILocationCollector interface with new ILocationProvider method

This change replaces ILocationCollector with a more general mechanism that
passes locations received from a provider to all other providers.
The network location provider now uses this to implement the location collector.
In the future, this could be used to inject network locations to the GPS
as aiding data.

This change also removes the now obsolete permission INSTALL_LOCATION_COLLECTOR.
