neverallow_macros: add watch* perms

In cases where directory read access has been neverallowed via
no_rw_dir_perms, also neverallow the various watch* permissions.
If read was disallowed by the neverallow assertions, there's an
assumption that watch was also intended to not be allowed. Make that
assumption explicit.
