Package aktualizr for Ubuntu 20.04 LTS

[charles2910]

We are going to package aktualizr for Ubuntu 20.04, 22.04, 24.04 and Debian bullseye/bookworm. Since it's a lot of stuff, I'd like to have each packaging in its own branch so toradex/focal, toradex/jammy, toradex/noble, toradex/bullseye and toradex/bookworm. This one is already named toradex/focal so I'm opening the MR to make it easier to see the differences and so we have a place to discuss/review everything.

All the changes are declared in d/changelog but the main ones are:

• Use the latest Toradex's aktualizr version in sync with what's going to be in the next quarterly release of Torizon OS;
• Use of reusable workflow (currently it doesn't work for armhf due to an weird interaction between qemu-user-static and CMake) so we can't get it to build via CI, though it builds correctly using native compilation + Ubuntu Focal schroot with sbuild;
• Remove bootloader update stuff and ostree options from config files;
• Moved config files to /etc/ to comply with FHS 3.0;
• Enabled offline updates.

In regards to

There is a clear workaround in the thread you linked [0]. Have you tried creating + applying a patch to add the -D_FILE_OFFSET_BITS=64 option?

@leonheldattoradex The solution is to recompile CMake with that flag. I don't think it's a viable solution for what the idea here is.
