Add the aria-readonly attribute to the x-screen element

This adds the aria-readonly attribute to x-screen element. Currently
on ChromeOS ChromeVox sends Search+Arrow key combinations through to
contenteditable regions as Up/Down/PgUp/PgDown keys. This works well for
normal contenteditable regions as it allows the cursor to be moved
through the editable region and when it reaches the top/bottom of the
region, ChromeVox will continue navigating through the rest of the
elements of the page. However in the case of hterm, the contenteditable
region is not really editable - the cursor is hidden and input events
(in particular PgUp/PgDown/Home/End) are consumed and preventDefaulted.
This results in element navigation not working well in ChromeVox.

Marking the region as aria-readonly gives ChromeVox an indication that
the content is actually not modifiable.
