Update test expectations for 3 SVG layout tests.
Update test expectations for 3 SVG layout tests.

- LayoutTests/svg/W3C-SVG-1.1/text-text-07-t.svg
- LayoutTests/svg/dom/svglist-exception-on-out-bounds-error.html

These tests regressed in WebKit r51627, and fixed in WebKit r51649. Now they
pass on all platforms.

- LayoutTests/svg/text/text-text-07-t.svg

Same as above, but this one passes only on WIN.

BUG=29344
