[Android 6.0] Bluetooth module doesn't add all needed permissions to AndroidManifest.xml

Beginning with Android 6.0, using Bluetooth requires permission ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION to be set, see e.g. http://stackoverflow.com/questions/33052811 .

When using the module bluetooth in qt, this needed permission is not set automatically. For example, the btscanner example doesn't find Bluetooth classic devices in Android 6.0, while in works fine with Android 5.0. Manually adding one of the above mentioned permissions solves this problem for Android 6.0, but I think this should work out of the box.
