ceph-windows: re-enable rbd-wnbd stamp test

We had to disable one of the rbd-wnbd tests while investigating
the reason why disks started coming up as read-only.

This was actually caused by the wnbd bus type, which changed from
virtual to SAS. The default Windows policy (offlineShared) doesn't
automatically bring online such disks, SAS being considered a
shared bus.

While at it, we're also enabling the new *Fs* tests, which use
a Windows partition instead of the raw block devices.
