Some PTS tests like A2DP/SNK/AVP/BI-03-C, A2DP/SNK/AVP/BI-08-C , …
request some specific rejection code to pass.
This commit adds an option to specify the rejection code during
AVDTP_SET_CONFIGURATION rejection.

E.g. "avtest --reject setconf --reject-code 195" to reject setconf with
INVALID_SAMPLING_FREQUENCY code.
