Fixing a few SVG layout tests.

Fixing a few SVG layout tests.

All the test below were missing a Z in the text diff to "take
closed (sub-)paths into account". This reflects a similar change
that was made upstream. For details see:
http://trac.webkit.org/changeset/38794

As for the image rebaselines, I will temporarily keep an img
diff of what changed vs. our current expected image baseline
under my home directory (internally), see:
upload\layout_tests\svg

The colourpicker test still has problems with the colored bars
not showing up so it has not been removed from the fixed list
(both img and text diff still fail, but at least text diff has
fewer failures).

The scrollbar test and the selectionlist test both have images
that are being resized and the baseline changes are due to
changes to our resampling code, I theorize.

And finally, the selectionlist test is not added to the fixed
list since it is crashing when run on the buildbot but not when
I run it. Needs further investigation.
