core/bluetooth: switch to use libdivecomputer rfcomm support

Browse source 
The Qt based implementation apparently got broken at some point and now fails
to connect to rfcomm dive computers like the Shearwater Petrel.

This uses the libdivecomputer rfcomm backend. Tested to work with bluez on
Linux as well as with the native Windows implementation.
