WPS: Add new PSK entries with wps=1 tag

Browse Source 
Now that hostapd wpa_psk_file has a new tag for identifying PSKs that
can be used with WPS, add that tag to new entries for PSKs from WPS.
This makes it clearer where the PSK came from and in addition, this
allows the same PSK to be assigned if the same Enrollee goes through WPS
provisioning again.
