manibuilder: Prepare for official multi-arch images

Now that we can use official multi-arch images prepare for tag names
matching the upstream ones. These will be prefixed with their respective
architecture, e.g. `ppc64le/`. To make the existing dockerfiles for
Debian and Ubuntu usable with the official images, remove their
`-debootstrap` suffix.
