bazel: download pseudo-version tool instead of "go build" (#1629)

Required for bootstrapping bazel stamping since we cannot use "bazel build" during the workspace_status command.
Adds a small script that builds the pseudo-version tool in bazel (without stamping) and uploads it to the mirror.
On the first bazel build with stamping, the pseudo-version tool is downloaded.
