third_party/sandboxroot: add mirror tool
This mirrors the sandbox RPMs into a GCS bucket any time we regenerate
it. Hopefully this stops the constant barrage of random 404s when Fedora
just happened to bump a library and all the mirrors lost its previous
version.
This tool is currently specific to our bazeldnf-based sandboxroot setup,
but could be extended to mirror all of our dependencies at some point.
As our mirror is the last in the list, it should only be used when a
file is missing from other mirrors. In the future, we should have some
job that alerts us when too many of our deps are missing from upstream
mirrors.
