Auto merge of #6884 - matthiaskrgr:lintcheck_crate, r=Manishearth

move lintcheck into its own crate

This pr:
* moves lintcheck out of `clippy dev` and into its own crate (`lintcheck`)  (I should have done this earlier :D)
* makes lintcheck terminate if it is not launched from the repo root (to prevent problems with wrong paths when using `cargo run` in the crate root)
* fixes json lint messages leaking the runners `$HOME` when a lint messages comes from a proc macro that originates from a crate inside the `$CARGO_CACHE`
* adds more documentation to lintchecks `README.md` and mentions lintcheck in `docs/basics.md`
