Some downstream distros eval'd version/version.sh to get at the shell variables
within their own build process. They can now `./build_dist.sh shellvars` to get
those.
Fixes#2058.

This makes it easier to integrate this version math into a submodule-ful
world. We'll continue to have regular git tags that parallel the information
in VERSION, so that builds out of this repository behave the same.

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.
