libcamera: v4l2_videodevice: Fix dangling file descriptor
The FileDescriptor constructor used in V4L2VideoDevice::exportDmabufFd()
creates a duplicate of the fd to store in the object. The original
fd returned by the VIDIOC_EXPBUF ioctl was never closed, and left
dangling. This would cause out of memory conditions if the camera stream
was repeatedly started and stopped.
This change closes the original fd explicitly, fixing the leak.
