Fix move partition right to left shrinks partition 1 MiB (#695078) 

When moving a MiB aligned primary partition from right to left, the
resulting partition was unexpectedly 1 MiB smaller in size.

From further testing, this occurred only if the move boundaries
overlapped the original partition boundaries.

In cases where the move did not overlap the original partition
boundaries, then the size remained the same.

Closes Bug #695078 - Move of MiB aligned partition right to left
                     yields unexpected shrink of 1 MiB
