Cleaned up udev-selinux patch

[Luke Kenneth Casson Leighton]

perhaps the style should be that the Makefile adds some code
add_selinux.c based on a configure-time option,

and that some #ifdefs in a header file call a function which
is a stub in the header if WITH_SELINUX is not defined.

bizarre_but_likely_quite_good_coding_style_never_encountered_before.h:

#ifdef WITH_SELINUX
int do_add_selinux_stuff(args) { return 0; }
#else
#define do_add_selinux_stuff the_real_add_selinux_stuff
#endif

and add_selinux.c contains:

int the_real_add_selinux_stuff(args)
{
	....

	return err;
}

Truth, honesty and respect are rare commodities that all spring from
the same well: Love.  If you love yourself and everyone and everything
around you, funnily and coincidentally enough, life gets a lot better.
