Fiemap gained support for passing in optional offset len
which denote the range requested, so this patch adds
testcases for this functionality. Aditionally, a special "ranged"
argument is added to the require_xfs_io_command which checks
for the presence of fiemap range support.

V6:
* Moved to generic tests and successfully ran against ext4/btrfs
* Use pwrite to create the holes to make it even more generic
V5:
* Drop changes to existing generic punch hole tests since
the new fiemap implementation don't require them
* Merge the common/rc change with this patch
* Added Data + Hole + Data and Hole + Data tests as per Eryu's request
* Adjusted output of some tests which fall in a hole, since holes are
truncated to passed range
* Simplified the logic to check for fiemap range support (Eryu)
V4:
* Added test description
* Added new test for past-eof behavior
* Removed supported_generic_fs line
* Switched to using the "ranged" param require
* Revert v3 changes
V3:
* Adjusted tests for '-r' fiemap param
* Tests for invalid -r combination
V2: No change
V1: No change
