Prior to Linux 4.5, the FICLONE etc ioctls were specific to BTRFS, and were implemented as regular filesystem-specific ioctls. This implements those ioctls directly in OpenZFS, allowing cloning to work on older kernels. There's no need to gate these behind version checks; on later kernels Linux will simply never deliver these ioctls, instead calling the approprate VFS op.
