maint: cleanup compare calls in test/du/inodes.sh

* test/du/inodes.sh: In the cases where compare() fails, that function
would show the unified diff automatically.  Therefore, remove the
excess "cat out".
In the cases where expecting an empty file, use compare() again
rather than the simpler "test -s" because possible error reports
will then include the file's content for the same reason as above.
