mgcp: Calculate the jitter with the formula/code from the appendix
Use a usec timestamp for the local time. The seconds to usec will swap over to the lower bits but this appears to be correct. The CLOCK_MONOTONIC is used to fulfill the RFC 3550 requirement even if it is a bit slower than the gettimeofday. Make sure to initialize transit in a way that the first transit time will be 0. Otherwise the jitter will contain the difference of the localtime and the remote time.
