xfsqa: Add fiemap exerciser

Browse Source 
Preliminary fiemap testing support based on a test util written by
Josef Bacik.

For now it's only run with preallocation disabled, because xfs has a
tendency to fill in holes with data blocks (EOF prealloc stuff I
think) and similar for explicit preallocation, so this is breaking
the preallocation tests for now, when it finds a "data" block where
it expects a preallocated block.
