prebuildifier and buildifier commands no longer work

[mrmeku]

It seems the version of com_github_bazelbuild_buildtools specified in the checksum was re-released with a different checksum. If you update to the correct checksum you can no longer run bazel build @com_github_bazelbuild_buildtools//buildifier successfully. Inspecting the download .zip file it seems like the command should work since there is in fact a build file in buildifier/BUILD. My working theory is that they somehow invalidated their workspace file when they rerelaesed and that's the reason the target cannot be found

Also note that using the latest commit of the repo didn't help the issue so I think that the issue still persists at HEAD
