[LTP] [PATCH 1/1] controllers/cgroup_fj: fix longtime wait cgroup_fj_proc.

[shuwang@redhat.com]

From: shuwang <shuwang@redhat.com>

On some machines, when many cgroup_fj_proc created on the background,
killall may failed to find and kill them all as the processes are
just created and not ready. And that will cause the ltp testrun wait
forever. So changed to use kill -9 instead.
