Make 'svnadmin verify --metadata-only' for FSFS f7 not only cover all
rev / pack file data but also the revprops.

In contrast to the rev / pack file checks, this will not detect all
possible modifications but it guarantees that no revprops are missing
or corrupted in a way that checkout etc. would fail.
