Provide universal Linux binaries

Currently, Core Lightning only provides Ubuntu and Fedora binaries, which is a bit odd since it's unlikely that it has any hard deps on those distros. I tried running Ubuntu 22.04 binaries on Arch and everything worked fine, except for some PostgreSQL dep which wasn't statically linked, apparently, so I had to install it via a package manager.

Bitcoin Core always provides universal Linux binaries, it would be nice if Core Lightning can follow the same pattern. Are there any technical reasons CL binaries aren't universal?
