Use new container and bootable-container productmd types

In https://github.com/release-engineering/productmd/pull/181 I
added new `bootable-container` and `container` types to
productmd. This makes pungi always use the bootable-container
type for ostree_container images (previously 'ociarchive'), and
default to using the container type for Kiwi-built oci.tar.xz
container images (previously 'docker').

This is a significant change for anything that relies on
productmd/fedfind conventions to 'identify' images, as these
images will now have a different identity. But I think it's a
valuable improvement in their identities. 'ociarchive' never made
any sense as an image 'type' - it's a format - and 'docker'
wasn't a very good type for images that are explicitly OCI
container images, not Docker-native ones. We also can now easily
distinguish between 'regular' container images and ones that are
intended to be bootable.
