Ensure QGeoPositionInfoSource::supportedPositioningMethodsChanged() on Android

This signal was added in Qt 5.12 but never emitted on Android.
Due to implementation issues this signal is emitted for each
provider change (e.g. twice if network and gps provider were disabled
when the entire location service is disabled)

Task-number: QTBUG-66427
Change-Id: I820b3187bfd8b8ab4facb053e2019e4f5c9736d0
