This is a regression testcase, it is added to check below case
and its variants:
- write 16k data into compressed file (data will be compressed)
- truncate file to 12k (truncate partial data in compressed cluster)
- truncate file to 20k
- verify data in range of [12k, 16k] to see whether data is all zero
or not

v2:
- add missing _require_xfs_io_command "truncate"
- add missing _require_fio $fio_config
- use $XFS_IO_PROG instead of xfs_io
- avoid mkfs&mount .. umount for each round test
