Treat an EOPNOTSUPP from fchflags() as a non-fatal case. Only warn about

Browse Source 
it if flags were explicitly specified on the command line.  Do not warn
if we were merely trying to preserve flags or remove UF_NODUMP.  NFS does
not support flags.

I'm not sure that this is ideal, but it should do for now.  Installing
a plain file onto a NFS server must work, we used to silently ignore the
attempt.  Doing a binary install looses the flags anyway since cpio
doens't preserve them with the cdrom/network images.
XXX make world should not use flags or chown/chgrp in the obj/tmp area.

This is based on a suggestion from Ken Merry <ken@plutotech.com>.
