Merged. It breaks build for some very old Linux systems (e.g. Debian 8,
CentOS 7), as HAVE_MPLS_KERNEL also checks for struct rtvia existence,
but these systems have obsolete/unsupported kernel versions anyways.

There is a question how handle feature divergence (primarily divergence
in which structures and enum values are defined for compile-time) in
Netlink between Linux and FreeBSD. I would prefer to not have autoconf
test for each such feature. For example we could probably remove
HAVE_MPLS_KERNEL altogether just for Linux (as the check is unnecessary
for non-obsolete kernels, but i am not sure about FreeBSD headers).
