Configure arcanist, linters, and unit engine

Summary:
Import `arcanist-go` into `vendor` to provide a unit engine and
`gofmt`/`govet` linters.

Lint with `golint`, `gofmt`, and `govet`.

Test Plan:
Run `arc lint --everything` and revel at the given advice.

Run `arc unit --everything` and hopefully nothing will explode.
