qgeotilefetchergooglemaps: small cleanup

Cleanup unused variables such as _versionGoogleMap and the
related logic.

QGeoTileFetcherGooglemaps::QGeoTileFetcherGooglemaps()
- remove some commented out code

QGeoTileFetcherGooglemaps::_googleVersionCompleted()
- remove regex calls that update the version strings,
yet said version strings are unused
