Do not exclude background images/colors when printing

Bug: 10969979

When we implemented printing, we used the default values from Chrome
which by default does not enable background colors and images. In
Chrome, such settings are enabled via GUI. Without this setting,
some pages look broken.
Since Webview does not provide an API for this setting,
not excluding background images seems the more reasonable approach.
