Subject: [PATCH] geos: pull upstream fix for gcc-13 build failure

Without the change build against `gcc-13` fails as:

    $ nix build --impure --expr 'with import ./. {}; geos.override { stdenv = gcc13Stdenv; }' -L
    ...
    /build/geos-3.11.2/include/geos/shape/fractal/HilbertEncoder.h:41:5: error: 'uint32_t' does not name a type
       41 |     uint32_t encode(const geom::Envelope* env);
          |     ^~~~~~~~
    /build/geos-3.11.2/include/geos/shape/fractal/HilbertEncoder.h:21:1: note: 'uint32_t' is defined in header '<cstdint>'; did you forget to '#include <cstdint>'?
