axolotl: Delete class_main init shell script

Apart from useless battery capacity faking, all this does is to
start/stop data and radio services based upon the baseband type
of several QCOM targets. Since all the supported targets in this
common tree are of the same type, simply start all relevant services
unconditionally and get rid of one more shell script.
