daemon: don't adjust oom-score if score is 0
This patch makes two changes if --oom-score-adj is set to 0

- do not adjust the oom-score-adjust cgroup for dockerd
- do not set the hard-coded -999 score for containerd if
  containerd is running as child process

Before this change:

oom-score-adj | dockerd       | containerd as child-process
--------------|---------------|----------------------------
-             | -500          | -500 (same as dockerd)
-100          | -100          | -100 (same as dockerd)
 0            |  0            | -999 (hard-coded default)

With this change:

oom-score-adj | dockerd       | containerd as child-process
--------------|---------------|----------------------------
-             | -500          | -500 (same as dockerd)
-100          | -100          | -100 (same as dockerd)
0             | not adjusted  | not adjusted

bef73d8b07 Wait for c8d process exit instead of polling API
In the containerd supervisor, instead of polling the healthcheck API
every 500 milliseconds we can just wait for the process to exit.

eaad3ee3cf Make sure timers are stopped after use.
`time.After` keeps a timer running until the specified duration is
completed. It also allocates a new timer on each call. This can wind up
leaving lots of uneccessary timers running in the background that are
not needed and consume resources.

Instead of `time.After`, use `time.NewTimer` so the timer can actually
be stopped.
In some of these cases it's not a big deal since the duraiton is really
short, but in others it is much worse.
