kata_proxy: Open a special goroutine do cmd.Wait
00d03c1 
Got a defunct kata-proxy after kata quit when VMCache is enabled.
The reason is vmcache server opens kata-proxy but doesn't wait it.

If VMCache is disabled, kata-runtime will quit before kata-proxy.
So it will not meet the issue.

Open a special goroutine do cmd.Wait in kataProxy.start to handle
the isssue.

Fixes: kata-containers#1678
