Adopted LFS3_ERR_BUSY for root-related errors

Browse Source 
Now that we use LFS3_ERR_BUSY for traversals, we no longer have an
excuse for not returning LFS3_ERR_BUSY on root-related errors:

- lfs3_remove(&lfs3, "/") => LFS3_ERR_BUSY
- lfs3_rename(&lfs3, "/", *) => LFS3_ERR_BUSY
- lfs3_rename(&lfs3, *, "/") => LFS3_ERR_BUSY

This better aligns with POSIX. Arguably we should have defined
LFS3_ERR_BUSY for this case anyways, it's not like additional error
codes cost much.

No code changes.
