mac80211: package virt_wifi driver

Add the necessary definitions to package the virt_wifi kernel module as
kmod package.

The virt_wifi module is useful to wrap an existing ethernet interface and
make it appear like a wireless device, which allows testing wireless related
userspace tools without actual wireless hardware.

In contrast to mac80211-hwsim, it allows forwarding "fake" wireless traffic
between different virtual machines, enabling virtual testing of complex
wireless topologies.
