Make sure ANATIVEWINDOW_QUERY_BUFFER_AGE is identified as VNDK API.

Previously when we switch to only expose VNDK header, the
ANativeWindow_query doesn't properly recognize
ANATIVEWINDOW_QUERY_BUFFER_AGE as a VNDK query and hence a -EINVAL was
returned. This patch makes sure it is identified and skipped to complete
the actual query.
