We already have vma_last_pgoff() which retrieves the last page offset
within a VMA.

However, code often wishes to span a page offset range, which requires the
exclusive end of this range.

So provide this in vma_end_pgoff() and update vma_last_pgoff() to use this
function.

Also update the VMA userland tests to reflect the change.

No functional change intended.
