META_MODE: Disable during installworld and similar.

META_MODE may create cookies during staging of files to WORLDTMP that would
also prevent installation of the files to the final DESTDIR, since the cookie
already exists.  This is not yet the case but will be soon.  Prevent other
similar issues by disabling META_MODE for any top-level install targets.
