Enforce the minTime parameter in LocationManager#requestLocationUpdates

There is a long history in Android, on both GED and non GED devices
of GPS providers ignoring the minTime parameter making location updates
every second. The problem is usually poor GPS drivers that claim to
do scheduling but then do not.

By making the minTime parameter strict (instead of a hint) we can add
a CTS test to ensure that udpates to not occur too frequently. I believe
this is the desired behavior from apps. If apps want to take advantage
of more frequent updates when another application asks for those updates
then it can use the passive provider.

The CTS test for GPS has already been submitted (as part of CTS Verifier).
