- Add USE_PACKAGE_DEPENDS_ONLY which will try installing dependencies
  from existing packages and not fallback on building from source.

  This is useful for package building tools such as poudriere and tinderbox
  to avoid building from source and confusing the build log, if a dependency
  failed to build for some reason.

  NOTE: USE_PACKAGE_DEPENDS has not changed here. It has always
        reverted to source if the package was not present.
