Automatically format BUILD file with buildifier lint mode

Use the -lint=fix option to automatically format the BUILD file.

buildifier version: 0.20.0
buildifier scm revision: db073457c5a56d810e46efc18bb93a4fd7aa7b5e

The .bzl files are omitted from formatting because the lint mode
removes declarations that are not used in the file itself, but are
referenced from other BUILD files.
