IuCS: remove IuUP LOOPBACK hack 

Since osmo-mgw now supports IuUP properly, and since we indicate IUFP in
the MGCP CRCX towars an IuCS RAN [1], we should no longer place the MGW
endpoint in loopback mode to hack up an IuUP Initialization.

This hack should have been removed along with [1].

[1] IUFP sent to MGW since this commit:
commit 3a02d29804
Refs: 1.8.0-13-g3a02d2980
Announce IuFP audio codec for UTRAN conns in CRCX towards MGW
