Reduce latency on starting WPS negotiation (TX EAPOL-Start earlier)

Reduce startWhen from 3 to 1 second if WPS is included in the build.
While this is done regardless of runtime WPS configuration, it is fine
to use a smaller value here in general. This cuts two seconds out from
WPS negotiation if the driver does not support addition of WPS IE into
the (Re)Association Request frame.
