Check for A2dp SNK UUID supported by remote

Check for A2dp sNK UUID supported by remote before proceeding
with A2dp SNK connection when DUT acts as A2dp SRC.
This change addresses the issue where Host being A2dp SRC is
seen trying connecting to other A2dp SRC repeatedly.
This will ensure that DUT being A2dp SRC does not try to connect
to A2dp SRC only peers.
