Adds wifi_network table to capture wifi network name.

[vdesouza]

Adds a table to get the current wifi network name since the Osquery wifi_info table no longer does this.

Includes the rest of the working fields in wifi_info so you only need to use this table.

See osquery issue #8220

Testing

osquery> SELECT * FROM wifi_network;
