MGCP_Test: test rtp directions separately in TC_ts101318_rfc5993_rtp_conversion
The testcase TC_ts101318_rfc5993_rtp_conversion tests the RTP packet
format conversion of ts101318 to rfc5993 and vice versa. At the moment
the testcase sends RTP packets in both directions at the same time. In
order to simplify the test and to make race conditions less likely, lets
test both directions separately and add some guard time.
