btrfs-progs: ioctl: add 32bit compat for SET_RECEIVED_SUBVOL

The ioctl value of SET_RECEIVED_SUBVOL will be different on 32bit
userspace and 64bit kernel. This is transparently handled on the kernel
side. We now define the same structure so we can verify the ioctl value.

The defined structure and ioctl should not be used. It is exists only
for testing purposes, documenting the mess and as a warning for the
future.
