typing: suppress a false error in mercurial/revlogutils/docket.py on py2
`ord()` wants bytes or str on py3, so I'm guessing it got confused by passing a
single byte instead of a one byte string. But this seems to work on 2.7.18
anyway.

#require cargo test-repo
$ . "$TESTDIR/helpers-testrepo.sh"
$ cd "$TESTDIR"/../rust
Check if Cargo.lock is up-to-date. Will fail with a 101 error code if not.
$ cargo check --locked --all --quiet
However most CIs will run `cargo build` or similar before running the tests, so we need to check if it was modified
$ testrepohg diff Cargo.lock
