* CVE-2022-45873.patch was backported from systemd/main, but it doesn't
build without another change from v252 when elfutils PACKAGECONFIG is
enabled.

* fixes:
| ../git/src/shared/elf-util.c: In function 'parse_elf_object':
| ../git/src/shared/elf-util.c:792:27: error: void value not ignored as it ought to be
| 792 | r = json_variant_dump(package_metadata, JSON_FORMAT_FLUSH, json_out, NULL);
| | ^
