Don't use setFixedLayoutSize in WebViewPlugin.

Don't use setFixedLayoutSize in WebViewPlugin.

The original usage of the method was added to fix a rendering issue
with the YouTube plugin: see http://crrev.com/2862031 .
Setting an appropriate viewport seems to work as well
and removes usage of a method I'm trying to remove.
