rust-embed: update to 8.9.0

This eliminates the proc-macro panic occasionally observed in CI,
instead ignoring paths which cannot be canonicalized.
See #12120.

While this does not address the underlying issue of why the proc-macro
fail happens, it should result in builds no longer failing, and since
they failed in the case where no embedding is desired, there should be
no issue with ignoring failed path canonicalization, since we do not
want to embed anything in these cases.
