The patch does two things at once:

- Switch from debhelper to debhelper-compat
- Lifting the compatibility level from 10 to 13 (for bookworm)

The later is causing trouble here. It seems to enable dh_dwz which
turns out to be broken for arm64. Some Debian bugs indicate it's
unfixable for bookworm...

For now no further action required. We can handle it here.

Just another "updating ISAR broke my layers" cycle. We're used to that
(sadly).
