Test that if we clone a file with some large extents into a file
that has many small extents, when the fs is nearly full, the clone
operation does not fail and produces the correct result.
This is motivated by a bug found in btrfs wich is fixed by the
following patches for the linux kernel:
[PATCH 1/2] Btrfs: factor out extent dropping code from hole punch handler
[PATCH 2/2] Btrfs: fix ENOSPC errors, leading to transaction aborts, when
cloning extents
The test currently passes on xfs.
