converting cap_set_pg() to for_each_task_pid()

[William Lee Irwin III]

I have a pending patch that converts cap_set_pg() to the
for_each_task_pid() API. Could you review this, and if it
pass, include it in your tree?

Thanks,
Bill

cap_set_pg() wants to find all processes in a given process group. This
converts it to use for_each_task_pid().
