Patch wpa-supplicant to set DEFAULT_AP_SCAN 0, the scan code doesn't handle

OpenBSD. Remove ap_scan=0 from default config as suggested by / ok dcoppa.

README still mentions ap_scan=0; as discussed with tb@ some institutions
provide sample config files which do include other ap_scan settings so
I think it's still helpful there.
