libiio: depend on avahi only when network backed is used

The `avahi` dependency is needed only when network backend is used.
The current dependency configuration will add the `avahi` dependency
regardless if network backend is used or not.

Move the `avahi` dependency to be part of `PACKAGECONFIG` configuration
which will insert the dependency only when needed.
