hostapd: Output hw_mode when using STATUS

Adding the hw_mode config parameter to the STATUS output to easier
determine the current hw_mode of an hostapd access-point. Currently
neither STATUS, GET hw_mode, nor GET_CONFIG output it.

Useful if the hostapd access point has been created with
wpa_ctrl_request() without using a *.conf file, like hostapd.conf.
