[RFC 14/34] wpa_supplicant: Check SYNC_CONFIG support

[Andrei Otcheretianski]

Currently, NAN support is assumed if NAN device interface is supported.
Since wpa_supplicant implementation is intended to work with new driver
and kernel only, make sure WPA_DRIVER_FLAGS_NAN_SUPPORT_SYNC_CONFIG flag
is set.
