In nmount(), internally convert the mount option: "rdonly" to "ro".

This makes updates mounts such as:
 "mount -u -o rdonly" work more like, "mount -u -o ro".

References to "-o rdonly" were changed to "-o ro" in revision 1.60 of
the mount(8) man page,
but some people still like to use "-o rdonly" since it was documented
in earlier versions of FreeBSD.
