Only auto-add counterpart GUIDs when required

Browse Source 
Doing this unconditionally means we accidentally 'bleed' one device mode into
another in a non-obvious way. For instance, a device might have two operating
modes with different GUIDs. If firmware is supplied for both modes in the same
cabinet archive then we might accidentally match the 'wrong' firmware when
the daemon has observed a mode switch and added the counterpart GUIDs.

We only really need the counterpart GUIDs when switching between Jabra, 8bitdo
and DFU devices where the DFU bootloader VID:PID is not manually tagged with
`CounterpartGuid` in a quirk file. In the general case lets keep it simple to
avoid difficult to find bugs.
