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)
