impl Default for ExitCode

As suggested here
  https://github.com/rust-lang/rust/pull/106425#issuecomment-1382952598

Needs FCP since this is an insta-stable impl.

Ideally we would have `impl From<ExitCode> for ExitStatus` and implement the default `ExitStatus` using that.   That is sadly not so easy because of the various strange confusions about `ExitCode` (unix: exit status) vs `ExitStatus` (unix: wait status) in the not-really-unix platforms in `library//src/sys/unix/process`.  I'll try to follow that up.
