Use commit-count based versioning for Mac builds (#5392)

Change version scheme from git describe (which picked up unrelated tags
like busybox-1.35.0) to commit-count based versions like 1.0.9548.

This gives automatic, always-incrementing version numbers that Sparkle
can properly compare for updates.
