Adjust cgroup cpu for Tizen

Latest public Tizen does not support cfs_period_us or cfs_quota_us because CONFIG_FAIR_GROUP_SCHED, CONFIG_CFS_BANDWIDTH are not enabled.
Thus, instead of strict cpu limitation using cfs_quota, use cpu_shares.
The cpu_shares of each NSJAIL process will be assigned according to ratio (cfs_quota/cfs_period)

This is temporary patch and is not well validated.
Tizen will consider to enable the kernel option for cfs_quota_us.
