[Merge] ~enr0n/ubuntu/+source/systemd:ubuntu-jammy into ~ubuntu-core-dev/ubuntu/+source/systemd:ubuntu-jammy

[Lukas Märdian]

The armhf failure is flaky, indeed. Thanks for running all the tests!

The changes LGTM overall, the new patches mostly match the upstream changes, but this diff (backport) looks a bit concerning to me:
```
--- a/src/libsystemd/libsystemd.sym
+++ b/src/libsystemd/libsystemd.sym
@@ -761,4 +761,5 @@ global:
         sd_device_get_trigger_uuid;
         sd_device_new_from_ifname;
         sd_device_new_from_ifindex;
+        sd_hwdb_new_from_path;
 } LIBSYSTEMD_248;
```

Are those versioned symbols? Could this lead to ABI incompatibilities with systemd v251/252? Could you please elaborate on this?
