Fix buildifier setup

[nettle]

Why:
Buildifier setup is a bit excessive.
It can be improved.

What:

• Remove duplicating aspect_rules_lint
• Uplift buildifier version
• Silence warnings from compiler

Addresses: #155

I agree that I did rush the buildifier patch a bit, and we would benefit from clearing it up.

However, I have some concerns about this change, see my comments.

[furtib]

Correct me if I'm wrong, but Buildifier versions are matching their Bazel "counterpart".

This is why I choose 6.4 to match the lowest version we still support.

[nettle]

I see. I'm actually not sure there are matching, but you might be right
