platform/x86: dell-wmi-base: Handle META key Lock/Unlock events 



Some Alienware devices have a key that locks/unlocks the Meta key. This
key triggers a WMI event that should be ignored by the kernel, as it's
handled by internally the firmware.

There is no known way of changing this default behavior. The firmware
would lock/unlock the Meta key, regardless of how the event is handled.

Tested on an Alienware x15 R1.
