fs: copy BTRFS_IOC_[SG]ET_FSLABEL to vfs
This retains 256 chars as the maximum size through the interface, which
is the btrfs limit and AFAIK exceeds any other filesystem's maximum
label size.
This just copies the ioctl for now and leaves it in place for btrfs
for the time being. A later patch will allow btrfs to use the new
common ioctl definition, but it may be sent after this is merged.
(Note, Reviewed-by's were originally given for the combined vfs+btrfs
patch, some license taken here.)
