configs/: replace archisodevice boot parameter with archisosearchuuid

`archisosearchuuid=` first searches for a matching UUID. If that fails,
then it mounts and looks for a `/boot/${archisosearchuuid}.uuid` file in
all detected block devices (in whatever order `blkid` lists them).

This implements "file system transposition" without relaying on boot
loader specific features and does not tie us to GRUB anymore.
