sh:handler=reflink does not work on zfs, even though zfs now supports cp --reflink

[erentar]

Title says all.

It is possible to make a file share extents using cp --reflink. The filesystem does not yet support the FIDEDUPERANGE kernel call, however sh:handler=reflink does not use this feature, so handler=reflink would work on zfs.

I suspect https://github.com/sahib/rmlint/blob/master/lib/utilities.c#L582 is relevant here.
