patch for Makefile.yp

[Antoine Jacoutot <ajacoutot_(_at_)_lphp_(_dot_)_org>]

Hi :)

I made a small patch to Makefile.yp so that only UID/GID between a certain 
range will be included in NIS maps.
I'm no developer and this was inspired from NetBSD, so I cannot guaranty this 
is how it should be done. Anyway, I find this usefull and it seems to work 
well (at least here).
I hope something like this could make it in the official sources.
Thanks.

Regards,

Antoine
