Bug 1378191 - Use JSON to send capabilities in "Marionette:listenersAttached" r=automatedtester

By not using the JSON format when sending the capabilities to the
frame script, the values cannot be correctly decoded. As result
the capabilities will be reset to their default values for the
listener, and can cause various failures.
