frame-xchg.c: fix build with glibc < 2.24

SOL_NETLINK is used since commit
87a198111a resulting in the following
build failure with glibc < 2.24:

src/frame-xchg.c: In function 'frame_watch_group_io_read':
src/frame-xchg.c:328:27: error: 'SOL_NETLINK' undeclared (first use in this function)
   if (cmsg->cmsg_level != SOL_NETLINK)
                           ^

This failure is due to glibc that doesn't support SOL_NETLINK before
version 2.24 and
f9b437d5ef
