bluez5: in SelectProperties, parse QoS values and pass to get_qos

Browse source 
The codec may need to take into account endpoint preferred QoS values,
so parse this information and pass it to the codec's get_qos.

All the QoS struct values need to be set, as otherwise BlueZ may pass
uninitialized zero values over the air, which devices can reject.  This
does not apply to CIG/CIS ids, which are automatically allocated by
default.

Fixes connecting to nrf5340 devkit, which requires a valid TargetLatency
value.
