Ensure we have a root partition when checking space

Partially addresses the "why doesn't CheckSpace work in a chroot" issue.
We can't make it work, but we can at least detect when it won't work by
checking for a partition for our given installation root. If we can't
determine the mountpoint for this, bail out with an error.
