libcamera: Fix build with gcc-15

Backport patch to fix the following error:
...
In file included from ../git/src/libcamera/dma_buf_allocator.cpp:9:
../git/include/libcamera/internal/dma_buf_allocator.h:66:19: error: 'uint64_t' has not been declared
   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>'
