scrolledwindow: Always add other scrollbar size...
... if we're not using indicators and the policy may be visible. Not
doing this if the policy may be invisible is incorrect as we need to
reserve the space anyway in case the scrolledwindow is allocated at
minimum size and the child size increases to show the scrollbar.
