Title: [test] update compile_all_aircrafts test

Also replace LOCAL_CFLAGS (which wasn't used anymore) with USER_CFLAGS (and add where missing).
Now you can e.g. test compile all aircrafts/targets in your conf and add extra flags like treating warnings as errors:

```
J=AUTO USER_CFLAGS=-Werror prove conf/examples
```
