I've pushed this to the NixOS repo on GitHub now.  Please let me know if this
causes any problems.

P.S. I do know that it won't work for people who have nscd disabled.  Without
nscd, programs need to have all active NSS modules in their $LD_LIBRARY_PATH.
Going through nscd gets rid of that problem (since only nscd has to be able to
find them).
