[PATCH BlueZ v1] client/print: Add decoding for UUID properties

[Luiz Augusto von Dentz <luiz.dentz@xxxxxxxxx>]

From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>

This adds proper decoding for UUID properties with usage of
bt_uuidstr_to_str so it can print the 'friendly' name as bellow:

bluetoothctl# transport.show /org/bluez/hci0/dev_94_DB_56_F7_F2_88/sep4/fd0
Transport /org/bluez/hci0/dev_94_DB_56_F7_F2_88/sep4/fd0
	UUID: Audio Source              (0000110a-0000-1000-8000-00805f9b34fb)
