Test helpers to match against regular expressions. #813

Extracted these from https://github.com/heroku/buildpacks-apt/pull/8 which uses these macros to test for output that cannot be done reliably using just assert_contains and assert_not_contains because of the presence of random variations like the names of temporary test folders.

@colincasey can you get CI passing? I gave it a quick skim and it looked fine otherwise. I'll give it a quick review as soon as CI is fixed. Can you ping me as soon as that is done? :)

@Malax yep, forgot to check a doc test and had accidentally applied a #[cfg(test)] to the unused dependency the linter was complaining about.
