libcamera: Fix build with gcc-15

Backport patch to fix the following error:

   66 |         void sync(uint64_t step);
      |                   ^~~~~~~~
../git/include/libcamera/internal/dma_buf_allocator.h:17:1: note: 'uint64_t' is defined in header '<cstdint>'; this is probably fixable by adding '#include <cstdint>'
