feat(modules/legacy/impermanence): Merge with the system config

Using the home-manager module uses a non-root fuse bindfs, which is
obviously slower than simply mounting the directories via bind
mounts. Besides, mounting them via the bindfs fuse mount, results in a
potential DOS, when this mount processes runs out of open file
descriptors (leading to the issue described in the `nix -> lix` commit.)
