[PATCH v2] respond Lenovo ThinkPad ?40 series' Fn+F8

[Adam Lee]

BugLink: http://bugs.launchpad.net/bugs/1396429

Lenovo ThinkPad ?40 series' wireless toggle key is not the classic
"ibm/hotkey HKEY" but "button/wlan WLAN", which only controls WLAN, this
patch makes it also controlling Bluetooth(only on ThinkPad) like the old
days.

v2: won't impact ibm-wireless event if a prior ThinkPad model has WiFi
but no Bluetooth.
