tests: Make dpp_pkex_test_fail and dpp_pkex_alloc_fail more robust

Wait for test/allocation failure for longer than the wait_fail_trigger()
default two seconds to allow DPP (in particular, PKEX) retransmission to
occur. This removes some issues where the previous wait was more or less
exactly the same duration as the retransmission interval and the first
Listen operation not always starting quickly enough to receive the first
frame.
