1. libcontainerd/supervisor: fix data race …

   The monitorDaemon() goroutine calls startContainerd() then blocks on
   <-daemonWaitCh to wait for it to exit. The startContainerd() function
   would (re)initialize the daemonWaitCh so a restarted containerd could be
   waited on. This implementation was race-free because startContainerd()
   would synchronously initialize the daemonWaitCh before returning. When
   the call to start the managed containerd process was moved into the
   waiter goroutine, the code to initialize the daemonWaitCh struct field
   was also moved into the goroutine. This introduced a race condition.
   
   Move the daemonWaitCh initialization to guarantee that it happens before
   the startContainerd() call returns.
