Print Preview Refresh: Remove Preview Area system dialog button

This button should not be shown on Chrome OS, since there is no system
dialog on that platform.

In the existing UI, it does not work on Windows, since Windows uses a
unique print preview -> system dialog path.

It is shown very infrequently on Mac and Linux, and these users
will still have the "Print with system dialog" link on the sidebar
available if this error state does occur.
