if_tunnel.h: add missing ams/byteorder.h include

commit 9bf35c8dddd56f7f247a27346f74f5adc18071f4 upstream.

When compiling userspace application which includes
if_tunnel.h and uses GRE_* defines you will get undefined
reference to __cpu_to_be16.

Fix this by adding missing #include <asm/byteorder.h>
