Updated @Flightradar24 Ansible cookbook

I had to wait a little while for the ARMv7 version for my EfikaMX devices, but they finally had time to compile it. Yay!

The updated cookbooks are on Github.

Changes (commits):

• Better key management
• fr24feed.ini
• No more separate dump1090 launch
• newest fr24 version
