Change statvfs test so it doesn't depend on device size.

Current statvfs test depended on a lot of filesystem details
which can change if the CHS of the underlying block device
changes (eg. with the switch from IDE -> virtio).  These are
not really necessary to test the call, so instead just check
for filesystem features.
