nl80211: Check 4-way handshake offload support

Set the WPA_DRIVER_FLAGS_4WAY_HANDSHAKE flag if the driver indicates
both 4-way handshake PSK and 802.1X support. Currently wpa_supplicant
doesn't distinguish between 4-way handshake for 802.1X and PSK, but
nl80211 API has different capabilities for each one.
