On Linux 2.4.x systems, where /usr/include/linux generally contain
unsanitized headers, 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.

We'll have no more releases of 2.4:

It's been announced several times that it has entered EOL.
