Accept FS usage figures within significant unallocated threshold (!49)
So far the read file system usage figures, read via the file system
interface classes using file system specific tools, have been checked to
the exact sector for:
0 <= used <= size
0 <= unused <= size
unallocated = 0
used + unused = size
However for JFS and NTFS this fails like this:

So JFS is reporting 2472 unallocated sectors in a size of 524288 sectors
and NTFS is reporting 8 unallocated sectors in the same size. This
exact issue is already solved for GParted so that it doesn't show a
small amount of unallocated space by commits [1][2] from Bug 499202 [3].
Fix the same way, use the accessors to the file system usage figures
which don't show unallocated space when it is below the significant
threshold.
[1] b5c80f18a9
Enhance calculation of significant unallocated space (#499202)
[2] 7ebedc4bb3
Don't show intrinsic unallocated space (#499202)
[3] Bug 499202 - gparted does not see the difference if partition size
differs from filesystem size

Closes !49 - Add file system interface tests
