auto-t: add sae test for non-acked commit

Browse Source 
This test simulates the scenario where IWDs commit is not acked which
exposes a hostapd bug that ultimately fails the connection. This behavior
can be seen by reverting the commit which works around this issue:

"sae: don't send commit in confirmed state"

With the above patch applied this test should pass.

Note: The existing timeout test was reused as it was not of much use
anyways. All it did was block auth/assoc frames and expect a failure
which didn't exercise any SAE logic anyways.
