[gtk+/wip/dboles/scrolledwindow-measure: 4/4] testsuite/scrolledwindow: Try non-overlay/non-auto

[Daniel Boles <dboles src gnome org>]

commit c78264fb6d2358e3d1062c7a06e648a85ca3e6dc

    testsuite/scrolledwindow: Try non-overlay/non-auto
    
    It was only testing the default configuration, where overlay scrolling
    is on and both scrollbars use POLICY_AUTOMATIC. We should also test the
    other 3 configurations that are available by including non-overlay
    scrollbars and/or those that use POLICY_ALWAYS.
