Subject: Fix handling of working dir

Buildah and podman build can create images without a working dir.

FROM fedora
WORKDIR /test

If you build this image with caching twice, the second time the image
will not have a working dir.

Similarly if you execute

podman run --workdir /foobar fedora

It blows up since the workingdir is not created automatically.

Finally there was duplicated code for getting the workingdir
out of an image, that this PR removes.
