recipes: cruft removal and seasonal cleanup

* Eliminate need for BBMASK - remove images requiring systemd/angstrom dependency
* Move ti-test packagegroup to proper location and update from latest Arago
* Move BoneScript and Bone GSG recipes to recipes-ti/beagleboard
* README in recipes-ti warns about unsupported nature of those packages
