fvp: Declare support for wifi.

Context.getSystemService("wifi") now throws an exception if the device
does not declare support for wifi. Moreover, even if I change the
implementation to return null instead of throwing, there are a number
of applications that fail to run correctly if the method returns null,
including Settings.

It seems like the rest of the system is pretty much assuming wifi
support at this point. So let's just pretend that we support wifi by
including android.hardware.wifi.xml in our vendor partition.
