network: add boolean for hs20 support

Browse Source 
Since NAI realms, Roaming Consortium and HESSID are defined in 802.11,
they are not a guarentee that the network is Hotspot 2.0. The indication
element in addition to these IE's gives a better idea of Hotspot 2.0
support. Now, when a BSS is added this is_hs20 boolean will get set to
true if the HS20 IE was found in the BSS.

Now, if is_hs20 is set AND one of NAI realms, roaming consortium, or
HESSID is set we know this is a hotspot 2.0 network.
