Subject: [PATCH] bib: mount `devtmpfs` inside the container too

This ensures that the new `partscan` feature in osbuild works. By
default the containers only have a static snapshot of /dev on a
tmpfs. This means that anything later added by losetup will be
missing inside the container.

It also means that https://github.com/osbuild/osbuild/pull/1468
can be reverted.
