[PATCH 1/2] build: fix libiptc build failure on old linux-glibc-devel headers

[Jan Engelhardt <jengelh@inai.de>]

On Debian 3.1, compilation of libiptc fails with

	  CC       libip4tc.lo
	In file included from libip4tc.c:113:
	libiptc.c:93: error: field `list' has incomplete type

This is because /usr/include/linux/list.h still existed at that time,
but has all its definitions stashed in __KERNEL__. Switching
linux_list.h's guards to another name resolves the problem.
