Auto merge of #6068 - eddyb:oopsie-daisy-stabilize, r=alexcrichton

Remove `fix::local_paths_no_fix`, as `crate_in_paths` is getting stabilized.

Needed for rust-lang/rust#54403 (blocking RC1).
Ideally we'd also clean up the tests, e.g. removing `#![feature(rust_2018_preview)]` and `is_nightly` checks, but it's easier to just remove the only failing test (because it tests the feature gate is needed).
