Hi all,

this is a rebased of the tests dave sent 5 years ago for the xfs post-EOF
block freeing.

Without the patches here:

https://lore.kernel.org/linux-xfs/20240623053532.857496-1-hch@lst.de/

all of the new tests will fail for the default configuration.

Changes since v1:
- fix _scratch_mkfs output redirection
- add _cleanup handlers
