Add support for Ubuntu 24.04 lts / noble

[hcoin]

Ubuntu has a new LTS release, 24.04 'noble'. Time to add a z-push .deb suite with 'the latest' to that repository, where presently it is missing. 2.7 builds cleanly in that release.

Thanks!

After we have 2.8 I'll look at packages. Also happy if someone is willing to do the builds.

Is it possible to install z-push on ubuntu 24.04? I tried using the sources files and using the installation description for ubuntu 22.04 but it didn't work
