version: use OSS repo's version when building. 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.

version: calculate version info without using git tags. 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.
