    iwinfo: fix WPA cipher reporting
    
    Within the Lua binding, use the same logic as the command line interface for
    reporting the used WPA ciphers. Instead of printing the intersection of
    pairwise and group ciphers, report both group and pairwise ciphers.
    
    This fixes a case where a connection which uses CCMP for pairwise and TKIP
    as groupwise cipher is getting reported as using the NONE cipher.
