qemu-config: turn into distcc-config and a package group

* Create a new packagegroup-core-device-devel which pulls in everything
  that qemu-config used to, with the exception of anjuta-remote-run -
  this is unlikely to be widely used
* Move the remainder of qemu-config to distcc-config and allow
  DISTCC_HOSTS to be configured via a variable of the same name
* Use SUMMARY instead of DESCRIPTION for single-line description since
  DESCRIPTION is defaulted from SUMMARY if not set
