When building with redo, also include the git commit hash
from the proprietary repo, so that we have a precise commit
that identifies all build info (including Go toolchain version).
Add a top-level build script demonstrating to downstream distros
how to burn the right information into builds.
Adjust `tailscale version` to print commit hashes when available.
Fixes#841.

I added them earlier while fighting our redo+xcode build which wasn't
picking up these files on incremental builds. It still isn't, but now I've
verified with full builds that no quotes is correct.
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.
