resource: process-group: Use taskstats instead of reading procfs

To lower the overhead of getting information about process, use
taskstats instead of reading procfs while building group list.
Moreover, two advantages can be gained as using taskstats directly:
 1. Lower number of copy
 2. Using taskstats accounting information without process driver
