[S] Change in osmo-bsc[master]: doc: overview: replace section TRAU mapper / E1 sub-channel muxer

This section seems to be copied from the OsmoNITB manual. In OsmoNITB everything was integrated in one binary, now dealing with TRAU frames is the task of the MGW. Let's remove the section but still leave a word about how Speech traffic is handled/relayed by OsmoBSC.
