packagegroup-core-basic: tidy up

* Remove packagegroup-core-basic-rpm - we already have a mechanism for
  ensuring that packaging tools are installed on the target if desired;
  we don't need a package group to bring them in as well (especially if
  packagegroup-core-basic is used with other packaging systems).
* Remove the poorly-named packagegroup-core-base-utils: we already get
  busybox via packagegroup-core-boot.
