include: linux: Update kernel headers to version v6.7
Update kernel headers to v6.7 using utils/update-kernel-headers.sh and re-instating libcamera local modifications. The V4L2_SUBDEV_CAP_MPLEXED flag has been renamed to V4L2_SUBDEV_CAP_STREAMS in the upstream streams API. Adapt the code base accordingly. The flag's numerical value hasn't changed, there is no ABI breakage introduced by the API update.
