[Autotest] Check Bluetooth naming format inside of bluetooth_IDCheck test.
A recent change appends some identifying numbers on the end of the
Bluetooth adapter alias. E.g. "Chromebook_1234" instead of just
"Chromebook".
The bluetooth_IDCheck test already verified the format of the ID.
This change makes it also verify the new naming convention.
Also, add a common utils function to get the device_type string
from /etc/lsb_release.
