This allows the caller to specify a uid and gid to use, even if there is no corresponding password entry. This will be useful in certain Xen configurations. We don't support just -runas <uid> because: (i) deprivileging without calling setgroups would be ineffective (ii) given only a uid we don't know what gid we ought to use (since uids may eppear in multiple passwd file entries with different gids).
