btrfs-progs: convert-test: Add test case for discontinuous hole extent
For ext* fs containing a large hole(larger than 128M), btrfs-convert
will only insert one 128M hole extent and skip the remaining.
This leads to discontinuous file extents.
Add test case for it, and since it's a pinpoint regression test case, no
combination of convert options nor checksum verification.
