Use only the standard buildifier binary name (#1245)
Use only the standard buildifier binary name (#1245)

Buildtools releases contain identical binaries `buildifier-linux-amd64` and `buildifier`, the latter is deprecated and will no longer be uploaded. It's safe to use just `buildifier-linux-amd64` now.
