Luke Granger-Brown a73ca3f43d feat(gerrit): Create Gerrit derivation.
This uses the actual Bazel build, using a variety of tricks and hacks to
make it actually work.

Bazel really wants to download linux binaries from the internet and run
them. In lieu of trying to fix the build system to not do this, we
instead put bazel inside an FHS environment, which allows the binaries
to find their dependencies.

We also have to patch a few things:

* We use build --nobuild instead of fetch, so we only fetch the
  dependencies we actually need for the build and not, say, Windows
  binaries.
* We don't remove rules_cc, because we need it as an external
  dependency, not bundled.
* We do some manual fixes on the cache before packing, because we need
  to remove some in-tree sources (so they don't cause the hash to break,
  since the hashes differ each time they're generated), and also remove
  some extraneous files.
* We explicitly turn off the repository and disk caches, because the
  .bazelrc at the root of the Gerrit tree turns them on, with paths
  pointing into the user's home directory.
* detzip is used instead of the zip binary for packing bower_components
  into an archive. detzip doesn't create entries for directories, and
  also doesn't store most metadata (timestamps, etc.), and uses store
  (i.e. uncompressed) compression only. It also sorts the file tree
  before writing them into the file.
