Patch

The following commit breaks compilation with Linux kernel headers from 2.6.37.

http://cgit.freedesktop.org/systemd/systemd/commit/?id=2e996f4d4b642c5682c608c9692ad2ffae398ab2

Compilation breaks with the output

In file included from src/nspawn/nspawn.c:42:0:
/usr/include/linux/netlink.h:31:2: error: unknown type name 'sa_family_t'

linux/netlink.h includes linux/socket.h for sa_family_t, but it is protected by
a #ifdef __KERNEL__

Newer kernels have fixed this issue such that linux/netlink.h is self
contained.

A work around is to include linux/netlink.h after sys/socket.h

I have attached a patch that does this, and verified that it fixes compilation
on the 2.6.37 kernel.
