gfxstream: fix build with gcc15

- add patch that adds missing `#include <cstdint>`, similar to what fedora does:
https://src.fedoraproject.org/rpms/gfxstream/raw/2c7cbc24596973e2efc8180af81e57ddfa24654b/f/fix_missing_cstdint.patch
(it applies, but somehow we hit more places with missing headers even
with that patch)

Fixes build failure with gcc15:
```
