Revert "MGCP: fix pattern warning"

For me this change causes MGCP parsing errors:

    setverdict(fail): pass -> fail reason: "Could not extract parameters for code "C""

Apparently the \r is after all necessary to parse MGCP. Maybe the '\r' is
implicit when an '\n' occurs, but the non-SDP part of MGCP has *only* '\r' line
breaks.

This reverts commit a9a52fff15227710e1a3a2e6222a388a3da11168.
