rustc: Fix another double-lint issue with crate::

[alexcrichton]

This commit fixes another issue in the absolute_path_not_starting_with_crate
lint where it warns twice about an import which may contain self. It turns out
there were a few more locations that needed updating to use root_id and
root_span introduced in #50970 and after that it looks to work like a charm!

Closes #50978
