[PATCH 2/9 v5] common/rc: add _require_fiemap and _extent_hole_counts

[Jaegeuk Kim <jaegeuk@kernel.org>]

This is to detect whether fiemap tool supports or not.

For the follwoing tests, this patch adds general script to get extent and
hole counts.

 xfs/137         (data vs filesize)
 xfs/138         (data vs filesize vs truncate)
 xfs/139         (data vs filesize vs partial truncate)
 xfs/140         (data vs filesize vs extending truncate)
 xfs/179         (data vs filesize w/ fsync)
 xfs/180         (data vs filesize w/ sync)
 xfs/182         (data vs filesize w/ recovery)
