I need to set the default uid/gid values for nobody/nogroup into kernel

wasn't a good thing to do.

I didn't realize that "nobody" was already defined in sys/conf.h and I can
use that.

I didn't know nobody was already there either.  They are only used by zfs,
while the others were originally only sed for devices.

There is no definition for "nogroup" in sys/conf.h.
Would it be ok to add
#define GID_NOGROUP  65533
to syy/conf.h?
(I know bde@ doesn't like expressing this as 65533, but that is what it is in 

sys/conf.h already has GID_NOBODY but it is subtly different from
GID_NOGROUP.  It seems to be a bug that zfs uses nobody's gid instead
of the gid nogroup which is used by no body.
