"make dist" fix for: no rule to make mgcp_common.h

Mark osmocom/mgcp_client/mgcp_common.h as nodist, so "make dist" will
not try to include it in the source tarball. This caused "make dist" to
fail in a clean osmo-mgw source tree with:
make[2]: *** No rule to make target 'osmocom/mgcp_client/mgcp_common.h', needed by 'distdir'.  Stop.

The file gets copied during make from osmocom/mgcp/mgcp_common.h (see
include/osmocom/mgcp_client/Makefile.am). Therefore it is not included
in the source tree and we don't need to distribute it.
