Added a place for example mac80211_hwsim test cases

The tests directory and its subdirectories contain a set of configuration
files that can be used to exercise various mac80211, hostapd, and
wpa_supplicant features. The test.txt file in each test directory describes
the particular test and includes the commands needed to run the test.
