Make the css-scrollbars reftest fail when properties are not implemented

This is the reftest part of
https://github.com/web-platform-tests/wpt/issues/44185

Similar work may be needed for testharness tests.

Note however that these are minimal modifications of the test that do
not account for overlay scrollbars anymore than the original tests did,
as dicussed in https://github.com/web-platform-tests/wpt/issues/44196

It's likely that some tests that used to pass with overlay scrollbars
regardless of what the browser did now fail even even if it does the
right thing. That's unfortunate, but it seems better than claiming a
PASS when we didn't effectively test anything, as we now at least have a
failure to investigate, even if it's a limitation in the test rather
than a bug in the browser.
