android: Don't show message for readonly files in non-experimental mode

Since editing is disabled in Android Viewer for non-experimental
mode anyway, there's no need to tell the user it's not possible
to edit a specific document if it's readonly.

Replace the 'usesTemporaryFile' method with a more explicit
'isReadOnlyMode' method since ToolbarController shouldn't
have to worry about implementation details like whether
temporary files are used and the new method will be reused in other
places in a follow-up commit as well.
