image_types_phosphor: Add SIGNING_PUBLIC_KEY

Support SIGNING_PUBLIC_KEY so that it generates an unsigned tarball.
Such tarball will be signed by separate tools as needed.

Tested:
* Do not define both SIGNING_KEY and SIGNING_PUBLIC_KEY, it generates
  the tarball as before with the dev key.
* Define SIGNING_PUBLIC_KEY and do not define SIGNING_KEY, it generates
  tarballs without signature.
* Define SIGNING_KEY and do not define SIGNING_PUBLIC_KEY, it generates
the tarball signed with the SIGNING_KEY.
* Define both SIGNING_KEY and SIGNING_PUBLIC_KEY, it gets error on
  building phosphor-image-signing recipe.
