Some OCI runtimes (cf. [1]) may tolerate container images that don't specify an entrypoint even if no entrypoint is given on the command line. In those cases, it's annoying for the user to have to pass a "" argument to podman. If no entrypoint is given, make the behavior the same as if an empty "" entrypoint was given.
