handshake: add flags/key index for extended key IDs

Browse Source 
ext_key_id_capable indicates the handshake has set the capability bit
in the RSN info. This will only be set if the AP also has the capability
set.

active_tk_index is the key index the AP chose in message 3. This is
now used for both legacy (always zero) and extended key IDs.
