Reduce minimumUpdateInterval for geoposition and geosatellite infos for android

For now, minimumUpdateInterval in QGeoPositionInfoSourceAndroid and QGeoSatelliteInfoSourceAndroid is set to 1000 (1 sec).

In our case we use external bluetooth gps receiver with update rate up to 20Hz and "Bluetooth GPS" play market application that send received from bluetooth nmea data to moc location so that our qt application can use default geo position info source and get this external coordinates.

But due to 1s restrictions we had to modify minimumUpdateInterval to 50 ms and rebuild Qt positioning module.

For sure default value should stay 1s - that is enough for almost all cases of internal gps on android, but as you see there is at least one user case that require lower minimumUpdateInterval.

It would be great if it is get available from the box. Thank you.
