ipfilter 4.1.16 ip_log.c compilation patch for Solaris

[Ian Donaldson <iand@ekit-inc.com>]

ip_log.c failed to compile on Solaris 10 until I applied this tweak...
(struct pollhead is not defined unless _KERNEL or _KMEMUSER is defined)

My compilation was only on Sol 10 but it looks like the problem
would occur in older Solaris's too (at least Sol8 and Sol9, by
inspection of <sys/poll.h>)
