Merge ~bluca/ubuntu/+source/systemd:jammy_repart into ubuntu/+source/systemd:ubuntu/jammy-devel

[Luca Boccassi]

Enable systemd-repart and ship it in a new systemd-repart package.

[Lukas Märdian (slyon)]

We got some response from the SRU team (@racb):

https://lists.ubuntu.com/archives/ubuntu-devel/2022-August/042250.html

Basically he suggests doing this change in a PPA/jammy-backports, or as a entirely new package:

* "what if you were to put systemd-repart as a new package into a PPA, or into jammy-backports?"
* "In general, adding new entirely new packages is considered OK from a regression risk perspective."

Would this work for you @bluca?

[Luca Boccassi (bluca)]

I've replied on list - I can work on updating this PR to add the new package

[Luca Boccassi (bluca)]

Updated to add a new systemd-repart package.

[Lukas Märdian (slyon)]

Thank you Luca, for splitting out the new files into its own systemd-repart binary.

I've staged the changes to provide an upgrade path in Kinetic++:
https://git.launchpad.net/~ubuntu-core-dev/ubuntu/+source/systemd/commit/?h=ubuntu-kinetic&id=2281670aa8007179170d5cc485bb94e3bbc3b63c

Furthermore, I've re-wrote d/changelog, using "gbp dch", as we usually do in Ubuntu.
And modified d/t/control to add the new binary as a test dependency to the "upstream-2" test case, this avoids skipping TEST-58-REPART.

I've rolled the change into the currently pending Jammy SRU at:
https://git.launchpad.net/~ubuntu-core-dev/ubuntu/+source/systemd

For reference, the new "libssl-dev" build dependency is required to allow for a hmac calculation in sd-repart. Alternatively, this commit could be backported to avoid the dependency: https://github.com/systemd/systemd/commit/ade99252e2cdd9eeff78566789008996d27e4dc0

Enable systemd-repart and ship it in a new systemd-repart package

Add fdisk as test dependency, needed by test-repart which calls sfdisk.
Add libfdisk-dev/libssl-dev as dependencies, needed for systemd-repart.
