Debootstrap fails for Debian testing/trixie/unstable

[Luca Boccassi]

[Impact]
On Jammy debootstrap now fails to create Debian trixie/testing/unstable as the usrmerge symlinks are shipped in base-files, like in Noble, so the debootstrap logic is incompatible.
Debootstrap in Jammy was already updated to deal with the same change in Noble via:

https://bugs.launchpad.net/ubuntu/+source/debootstrap/+bug/2054925
https://git.launchpad.net/ubuntu/+source/debootstrap/commit/?h=applied/ubuntu/jammy-devel&id=9dcbc77446c78935407d736ac1497b625a82d51e

The same change needs to be applied to the Debian script for testing/unstable in Jammy

[Test plan]
Running debootstrap for bookworm/testing/unstable successfully, resulting in a correct usr-merged system. With the patch this works fine, without the patch testing/unstable fail.

[Where problems could occur]
We do not anticipate any regressions as we replace the previous *) case for usrmerge for trixie/testing/unstable, so previous versions are unaffected.
That said, this is a different approach than bookworm and older, so there could be unforeseen results.

The new package from jammy-proposed works as expected
