constraints: Use "orig" rectangle for interactive resize

Browse Source 
Bug 448183 fixed an issue with _NET_WM_MOVERESIZE_WINDOW not moving a
window by basing the resize on the current (new) rectangle instead of
the original rectangle.

While this fixes the issue with _NET_WM_MOVERESIZE_WINDOW, this also
causes windows with a size increment to move when the resize also
implies a move, such windows might drift while resizing.

Make sure to use the current rectangle for non-interactive resizes only.
