The option causes a measurable slowdown. Macos is, by far, the most expensive platform for CI, therefore it doesn't make sense to run such a test there. d3b111e3205 used a small segment size for two tasks, one with autoconf, one with meson. In hindsight that is a bit overkill, it's unlikely that the option would silently break. Thus don't move the -Dsegsize_blocks=6, just remove it. I did however change the autoconf test to use 6 instead of 8 blocks, as long as we allow it, a non-power-of-two test seems like a good idea. While at it, add a comment explaining why we use a small segment size for CI.
