libcamera: v4l2_device: Make fd() function const
There are use cases for getting the file descriptor of a const V4L2Device instance, for instance to print it in a log. Make the function const. There's little risk of abuse here (as in code then performing operations on the file descriptors that conceptually modify the V4L2 device), as the fd() function is protected.
