Apply buildifier to existing files (#1090)

Before we start applying lint checks for BUILD.bazel and *.bzl files in
GitHub Actions (#1089), this commit aims to fix existing lint errors by
actually applying 'buildifier' [1] locally.

This is just a style fix in build files. There must be no observable
behavior change in artifacts.
