Pi zero w and activate-cron.sh (pi24 image)

[wahlm]

I recently did a setup of a raspberry pi zero w and the pi24-2.2.0.img image. Unfortunately it did not work because of a typo in /usr/lib/fr24/activate-cron.sh. The zero w does not have an ethernet interface. The script checks additionally for a wlan network device, but the result is never put to variable DEV. This leads to not getting a MAC address later. After a quick fix the setup was successful. See the diff below. Probably a correction in the image will help other zero w users.
