tests: Speed up hostapd_oom_loop tests

At some point, these hostapd_oom_* test cases started to fail with
wpa_msg() allocation failure for the AP-ENABLED event. This resulted in
unnecessary long test execution (waiting 30 seconds for an event that
was dropped). Speed this up by using a shorter timeout.
