autotest: Use Cras DBus API to detect audio loopback dongle
We should deprecate the cras_test_client --dump_server_info usage in
autotest because the main purpose of dump_server_info is for debugging,
and the format will be changed from time to time.
Use output returned from DBus API instead, which is much more stable.
BUG=chromium:491931
TEST=./cli/atest host create <DUT_IP>; ./cli/atest stat <DUT_IP>; Check
'audio_loopback_dongle' label is detected.
