Subject: [PATCH] cluster/tools/rook-s3cmd-config: build using bazel

This turns the existing script into a proper sh_binary, and injects
dependencies (kubectl and jq) as deps into it.

This change also pulls in BUILDfiles for jq, and a dep (oniguruma) into
//third_party, and adds buildable external repositories for them.

The jq/oniguruma BUILDfiles are lifted from
https://github.com/attilaolah/bazel-tools/.
