bluetooth: Consider adapter UUIDs when evaluating profile support

Browse source 
The remote device list of UUIDs reflects which profiles are supported by
the remote device alone. We currently rely solely on this list to decide
if a certain card profile is supported, and thus should be created and
get connected.

This used to be accurate when the Bluetooth modules were first written,
but now BlueZ is more dynamic and local profile support can be added or
removed during runtime. The adapter's list of UUIDs is an accurate
representation of the profiles supported by the local host at a certain
moment.

This commit combines the list of UUIDs supported by remote device and
the list of UUIDs supported by the local host to determined whether a
Bluetooth profile is actually supported or not, and whether it should be
expected to get connected during device connection.
