hack to work around RA quirk

This is a gross hack to work around rust-lang/rust-analyzer#10793: calling `cargo-miri/miri` does the same thing as calling `./miri`.

`@oli-obk` this is the best I could come up with... not sure if we want to have this in the repo. I am also okay with carrying `cargo-miri/miri` locally.
