Move mount_portalfs, mount_smbfs, and mount_nwfs from sbin to usr.sbin.

They don't have alot of reason to be in sbin and contribute to library
bloat in the dynamic case. If you are using any of these filesystem
type to hold your /usr, please seek professional help.

The actual code was repo-copied by joe.
