cgroupfs-mount: new package

This package consists of scripts that setup cgroups at boot without
doing any cgroup management or classification of tasks into cgroups

Signed-off-by: Niranjan Reddy <niranjan.reddy@rockwellcollins.com>
[Thomas:
 - rename to cgroupfs-mount to match upstream
 - add proper hash, since hashes should be added for github sourced
   packages
 - fix minor typos in the init script
 - fix the license file information.]
