`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.

Issue was caused when exec is tarted, exits, then stated again.
In this case, `Close` is called twice, which closes a channel twice.
Changes execConfig.ExitCode to a pointer so we can test if the it has
been set or not.
This allows us to return early when the exec has already been run.
