Function ichwh::symlink_chain

pub async fn symlink_chain<'_>(bin: &'_ str) -> IchwhResult<Vec<PathBuf>>

Find a binary and, if it's a symlink, all intermediate files in its chain. Returns an ordered Vec, with the first simlink at index 0 and the final binary at the end. If a symlink is encountered with a relative path, it assumes the path is relative to the symlink's parent.
