[PATCH 4/4] build: avoid spurious hard dependency on libosmo-sccp

[Andreas Rottmann]

From: Andreas Rottmann <a.rottmann at gmx.at>

In the libfilter source code, which is built regardless of --enable-nat,
headers from libosmo-sccp were used, thus causing a build failure (see
below) when building without --enable-nat, and libosmo-sccp not being
installed (or being installed in a prefix not otherwise included in the
build).

The build fails like this:

In file included from ../../../src/libfilter/bsc_msg_filter.c:27:0:
../../../include/openbsc/bsc_nat_sccp.h:27:37: fatal error: osmocom/sccp/sccp_types.h: No such file or directory

As the includes seem not to be actually needed, this change fixes the
issue by just omitting them.
