eapol: Simplify GTK install callback
...
Instead of passing in the RSN/WPA elements, simply pass in the
configured cipher. This will make the implementation of the install_gtk
callback much simpler.

eapol: Extract & keep track of desired ciphers

When our own WPA IE or RSN IE are set, extract group and pairwise
ciphers. These ciphers are the ones we desire to use for the secure
connection.

eapol: Drop unneded check in verify_ptk_4_of_4
...
Step 4 is always sent without encrypted Key Data according to Section
11.6.6.5. In the case of WPA, Encrypted Key Data field is reserved, and
should always be 0. Thus it is safe to drop the !is_wpa condition.
