Fix REAL_HP on other architectures. Add bookworm arm64 to CI pipeline.

@gladk with this small fix the REAL_HP should work now on other architectures. Let's see the pipeline. You should be able to enable REAL_HP back on the debian build servers.

I didn't manage to build docker images for s390x and ppc64el. There are some errors with libseccomp2 package on the system hosting qemu. I have to wait until they fix it. But I add arm64 to CI pipeline.

I have tested this fix locally in chroot on ppc64el and arm64. I don't have chroot for s390x right now. In case of problems I will prepare one.
