message: Add additional raw error mappings for the nightly `io_error_more` feature
  Some crates are using nightly and failing when mapping these errors,
  for example <https://miri.saethlin.dev/?crate=remove_dir_all&version=0.7.0>:
  ```
  error: unsupported operation: io error NotADirectory cannot be translated into a raw os error
  --> /root/.rustup/toolchains/miri/lib/rustlib/src/rust/library/std/src/sys/unix/fs.rs:1203:19
  ```
