wifi: mac80211: add key flags to debugfs

Browse Source 
Since there are two sets of key flags, one for the driver
and one internal to mac80211, add the first set in debugfs
as well. This will be used by hwsim tests to determine if
a key is pairwise or not, since the next changes will make
mac80211 use only per-STA GTKs.
