Yacin Tmimi 737e6f7046 Improve out of line module resolution
Fixes 5119

When the directory structure was laid out as follows:

```
dir
 |---mod_a
 |    |---sub_mod_1.rs
 |    |---sub_mod_2.rs
 |---mod_a.rs
```

And ``mod_a.rs`` contains the following content:

```rust
mod mod_a {
    mod sub_mod_1;
    mod sub_mod_2;
}
```

rustfmt previously tried to find ``sub_mod_1.rs`` and ``sub_mod_2.rs``
in ``./mod_a/mod_a/``. This directory does not exist and this caused
rustfmt to fail with the error message:

    Error writing files: failed to resolve mod

Now, both ``sub_mod_1.rs`` and ``sub_mod_2.rs`` are resolved correctly
and found at ``mod_a/sub_mod_1.rs`` and ``mod_a/sub_mod_2.rs``.
