Fix supernod dependencies and add vbmetanod

- The supernod target incorrectly specified all the images it combines
  as dependencies. This is not wanted for a "nod" style of target which
  is meant to not care about dependencies. It is assumed the person
  knows what they are doing when using this target.
- The vbmetaimage-nodeps target did not function as it called in to a
  method which used $@ as the output name, assuming it was only used by
  the actual out/target/product/.../vbmeta.img rule. This was updated to
  take the output name as a parameter the same way the snod rule works.
- The vbmetanod target did not exist so it was added as a clone of
  vbmetaimage-nodeps.
