packagegroups: Move bootchart, return babeltrace and latencytop

* moved from packagegroup-core-tools-profile, because
  packagegroup-core-tools-profile contains only work arounds for issues
  in danny release and now after upgrade to dylan we don't need this
  .bbappend
* this will return babeltrace and latencytop, x11 DISTRO_FEATURE isn't
  needed after:

  http://git.openembedded.org/openembedded-core/commit/?id=1b41a4660d0dd8f1863bb94d08562927cc108ee1
* packagegroup-core-tools-profile version will go backwards, because
  we're using PR_appends
