package/raptor: add patches for CVE-2024-57822, CVE-2024-57823

This fixes the following vulnerabilities:
- CVE-2024-57822:
    In Raptor RDF Syntax Library through 2.0.16, there is a heap-based
    buffer over-read when parsing triples with the nquads parser in
    raptor_ntriples_parse_term_internal().
    https://www.cve.org/CVERecord?id=CVE-2024-57822

- CVE-2024-57823:
    In Raptor RDF Syntax Library through 2.0.16, there is an integer
    underflow when normalizing a URI with the turtle parser in
    raptor_uri_normalize_path().
