[gtk+] testsuite/scrolledwindow—Test non-overlay/non-auto

[Daniel Boles <dboles src gnome org>]

commit 5a6e6689ec9c3158832848f951b259cd1eeaa777

    testsuite/scrolledwindow—Test non-overlay/non-auto
    
    It was only testing the default configuration where overlay-scrolling is
    TRUE and the policy is POLICY_AUTOMATIC. We should also test FALSE and
    POLICY_ALWAYS. This commit adds those tests and makes the !overlay &&
    POLICY_ALWAYS case pass by excluding the size of the relevant scrollbar,
    as we are only interested in whether the content size is as requested.
