read_config_file(): Update to get the config from `config.toml`

Use XDG handling from `state_load_map_group()` to do basically the same
thing here for reading the config from a `config.toml` file.

Use 'error-chain' to handle the `Result`s more easily. No more nested
pattern matching, we'll just have to unwrap one `Result` and write the
error to stderr in an FFI function.
