Update default wpa_group_rekey to once-per-day when using CCMP/GCMP

Browse source 
The default value for GTK rekeying period was previously hardcoded to
600 seconds for all cases. Leave that short value only for TKIP as group
cipher while moving to the IEEE 802.11 default value of 86400 seconds
(once-per-day) for CCMP/GCMP.
