Add Github CI for Haiku r1beta5 and nightly using build_matrix.sh

clang 17 doesn't work as expected on x86.

Thank you for preparing these changes. Do you know if there is a feasible way to implement this using Buildbot and a standalone VM?

[korli]

Sorry, I don't know much about buildbot.

For reference, on my old PC with 4 cores and ccache tcpdump build matrix in a Haiku VM took almost 70 minutes. Given a budget of 2000 minutes per month, that would be 28 builds per month.

Let me have a look and think about it.

Github CI does it in 26 minutes: https://github.com/korli/tcpdump/actions/runs/8349002774 What's the problem with Github actions?

Please don't use 'git merge', always use 'git rebase' (See CONTRIBUTING.md)

I suspected there is a way to extend an existing CI facility for Haiku instead of introducing an additional CI facility just for Haiku (because there are 4 of them already). One such way would be using a Haiku image in Cirrus CI. Here is the document and the script that prove such an image exists, although there seems to be a bug.

Please remove merge, use rebase.
