Dockerfile's ENTRYPOINT statement supports also a list of strings. This
patch implements this behavior for oci-container-configuration.
* oci/services/containers.scm (string-or-list-of-strings?): New
procedure.
(oci-container-configuration)[entrypoint]: Change field type to
maybe-string-or-list-of-strings.
(oci-container-configuration->options): Use it.
* doc/guix.texi: Document it.
