sys-apps/iproute2: Fix compile error w/ sys-libs/uclibc-ng

Local compatibility fix for sys-apps/iproute2-4.12.0 under a
sys-libs/uclibc-ng system where netinet/in.h is missing a definition
for 'IPPROTO_MH'.

+Subject: [PATCH] Fix build with uClibc-ng
+
+Add a local definition for IPPROTO_MH to fix build with uClibc-ng. As of
+version 1.0.25, the uClibc-ng netinet/in.h header does not provide this
+definition. The kernel provided definition is masked by libc-compat.h. Add
+this local fix until uClibc-ng syncs netinet/in.h with glibc.
+
+This partially reverts upstream commit a9ae195a2169 (xfrm: get #define's from
+linux includes)
