Fix broken QBluetoothServiceInfo::serviceClassUuids() call

It never returned a valid entry due to wrong QVariant conversion.
The patch changes the public header with a potential to break BC. A
formerly inline function was reimplemented and is no longer inline.
This should be safe though as older header versions can still use
the previous implementation.
