If container is not in correct state podman exec should exit with 126

Browse Source 
This way a tool can determine if the container exists or not, but is in the
wrong state.

Since 126 is documeted as:
**_126_** if the **_contained command_** cannot be invoked

It makes sense that the container would exit with this state.
