libpod: honor runtime_path from libpod.conf
Add backward compatibility for `runtime_path` that was used by older versions of Podman. The issue was introduced with: 650cf122e1b33f4d8f4426ee1cc1a4bf00c14798 If `runtime_path` is specified, it overrides any other configuration and a warning is printed. It should be considered deprecated and will be removed in future. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
