storage_util: Prefer generic FICLONE over btrfs/xfs defines

After my change to the original patch that resulted in commit
8ed874b39b it was brought to my attention that all three defines
are the same: FICLONE = BTRFS_IOC_CLONE = XFS_IOC_CLONE (as
documented in ioctl_ficlone(2)). Therefore we should prefer
generic FICLONE over 'specific' defines for btrfs/xfs.
