gio/tests: add some more async stream tests

Add read_async() and skip_async() tests to buffered-input-stream.

Fix and re-enable filter-streams's existing close_async() tests, and
add read_async(), skip_async(), and write_async() tests as well. Also,
redo the tests to use dummy GFilterInputStream and GFilterOutputStream
subclasses rather than GBufferedInput/OutputStream, so that we're
testing the base filter stream implementations of everything (since
the buffered stream overrides are already getting tested in the
buffered-input-stream and buffered-output-stream tests anyway).

Add a skip_async() test to unix-streams. (This one would crash without
the bugfix in the previous commit.)
