hostapd: Output country_code and country3 when using STATUS

Add the country_code and country3 config parameter to the STATUS output
to easier determine the current values for each of an hostapd
access point. Currently neither STATUS, GET [country_code/country3] nor
GET_CONFIG output it.

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