conmon: Make --exit-dir optional 

CRI-O's server relies on this for creation attempts, but it can set
the option.  conmon itself doesn't need to care one way or the other.
Perhaps it is being called by a process that doesn't care about the
container exit code or has another way to access that information.
With this commit, we trust callers to set --exit-dir if they want it,
instead of requiring non-exec callers to set it.
