Subject: [PATCH] Add context to get_toml_path() error (#5207)

* rustfmt: print full error chain

* Add context to get_toml_path() error

Instead of an error like:

```
Permission denied (os error 13)
```

Gives error like:

```
Failed to get metadata for config file "/root/.rustfmt.toml": Permission denied (os error 13)
```
