This broke clippy CI rust-lang/rust-clippy#4270

Ah, I didn't realize others were testing hyper master for things. As part of #1836, master disabled running its tests in CI since they aren't updated yet.

I've seen the pattern of moving disabled things to a tests_disabled directory in other projects, I think doing that here would fix this?

[seanmonstar]

Ok, I've manually disabled tests/examples that aren't working, and added cargo build --all-targets to CI to be sure :D
