Run cgroups cleanup code in WatchDog.

After CL:45672, the watchdog process doesn't run cgroups cleanup code. This
means that orphaned child processes are left around when you press the 'stop'
button on a builder.

BUG=chromium:223044
TEST=Run test case where child process switched the sid and verify that this
     child gets killed.
