fuzzy: add a custom xfs find utility for scrub stress tests
Create a new find(1) like utility that doesn't crash on directory tree
changes (like find does due to bugs in its loop detector) and actually
implements the custom xfs attribute predicates that we need for scrub
stress tests. This program will be needed for a future patch where we
add stress tests for scrub and repair of file metadata.
