Fix false positive in explicit_counter_loop lint
When the counter was used in a closure after the loop the lint didn't detect the
usage of the counter correctly.

Only pass `--extern` flags for rlibs in target deps directory
It seems like there are proc macros/build scripts using serde: https://github.com/rust-lang/rust/pull/66207#issuecomment-552159692
This fix the build error by only passing `--extern` flags for rlibs in target deps directory (if available, otherwise host deps directory).

build macOS on bors branches only
Clippy is portable enough. It is rare to see Clippy builds' broke
on *nix OSes. Testing macOS build on auto and try branch is
enough.

Remove `extern crate clippy_lints` from tests
This causes rustc's build system to fail because it still tries to load the crate as a plugin: https://github.com/rust-lang/rust/pull/66158#issuecomment-550415160 . I'm not sure _why_ this happens, but for a short term fix we should remove these.
In one case it was just a convenient crate to use so i picked a different test. In another it was load-bearing, I had to delete the test. Idk if there's a better way around this.

Fix Deprecated lints don't expand
### Move doc comments inside of declare_deprecated_lint macros so that they are picked up by lintlib.py
### fixes#4748
Unable to `cargo test` locally (I'm on NixOS, and keep getting errors that are similar to those #4714 might solve) but I have verified that all deprecated lints can now be expanded like other lints.
changelog: Show deprecated lints in lint documentation again
