rust/cargo: ignore RUSTSEC-2026-0009 for time crate

cargo audit reports this security issue with the time crate but Suricata
remains unaffected as no influenced fn is used by Suricata.
Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0009

The MSRV for newer time crate versions are higher than the MSRV for
Suricata right now: 1.75.0

Hence, the best course of action is to suppress this warning.
