kernel include if_arp.h

i was trying to compile squid-2.5.STABLE3 with arp acl support in my i686-pc-linux-gnu box.

squid/src/acl.c include <linux/if_arp.h>
so while compiling i got warning that an include file should not be used outside the kernel

modifying linux/if_arp.h:

#ifdef __KERNEL__
#include <linux/netdevice.h>
#endif

resolve the problem
