bluetooth: Abstract transport access types inside bluetooth-util

Browse source 
Transports can be acquired with different access rights, but in practice
"rw" was always used inside module-bluetooth-device. In addition, this
feature is removed in BlueZ 5.0 and therefore it is convenient to
abstract all this inside bluetooth-util.
