Our primary version format is git describe --long --abbrev=9.
Our Apple scheme is:
(major+100).minor.(patch*10,000+gitDescribeCommits).
This CL gets rid of the third, which was:
major.minor.(patch*10,000+gitDescribeCommits).
Now the "About" box in the macOS app shows the same version that we
show on pkgs.tailscale.com, userz, changelog, etc.
This will be more important once/if we get standalone DMG downloads
for macOS on pkgs.tailscale.com.
