Ensure WORKDIR from images is created

A recent crun change stopped the creation of the container's
working directory if it does not exist. This is arguably correct
for user-specified directories, to protect against typos; it is
definitely not correct for image WORKDIR, where the image author
definitely intended for the directory to be used.

This makes Podman create the working directory and chown it to
container root, if it does not already exist, and only if it was
specified by an image, not the user.
