Subject: [PATCH] crossfire-server: fix build due to missing `cstdint` include

GCC 13 stopped including `cstdint` (and other headers) transitively
in most scenarios, causing build failures in programs that relied
on that behavior.

This change adds a missing `cstdint` include via patch to the
`crossfire-server` source, fixing such a build failure.
