Refactor the filetests harness so that it can be run as part of `cargo test`. And begin reorganizing the test harness code in preparation for moving it out of the src directory. - Test subcommand files are now named `test_*.rs`. - cton-util subcommand files now just export their `run` and nothing else. - src/filetest/mod.rs now also just exports `run` and nothing else. - Tests are now run in release mode (with debug assertions enabled).
