btrfs-progs: tests: add image with explicit hole to fsck-tests/065-valid-log-tree

Browse Source 
Adds a test that btrfs check doesn't flag a file extent in the log tree as
an error because of no corresponding csum entry, if the file extent is
actually an explicit hole. See commit f6dc0e86.

The log tree in hole.img.xz:
