Label /data/misc/wifi/sockets with wpa_socket.
This will ensure that any sockets created in this directory
will default to wpa_socket unless a type_transition is defined.
Define a type transition for system_server to keep its separate
system_wpa_socket type assigned for its socket. Allow wpa
to create and unlink sockets in the directory. We leave the
already existing rules for wifi_data_file in place for compatibility
with existing devices that have wifi_data_file on /data/misc/wifi/sockets.
