linux/pkt_cls.h indirectly includes linux/stddef.h, which may define
__always_inline when using Linux kernel headers 4.6 or later.
netinet/in.h indirectly includes sys/cdefs.h, which before Glibc 2.24
would unconditionally define __always_inline.
This combination of headers causes compilation failure. Resolve the
issue by placing the netinet/in.h include above linux/pkt_cls.h.
Sourceware-BZ: #20215.
