Marco Vedovati 4f56964d55 libpod: fix hang on container start and attach ...

When a container is attached upon start, the WaitGroup counter may
never be decremented if an error is raised before start, causing
the caller to hang.
Synchronize with the start & attach goroutine using a channel, to be
able to detect failures before start.
