Pei Su 818faba77e Fix race condition in execCommandGC ...

`daemon.execCommandGC`
The daemon object (grep execCommandGC) iterate over a map
(grep execCommands.Commands) in a goroutine.
Lock can't protect concurrency access in this case.
Exec command storage object should return a copy of commands instead.
