replace library used to interact with tray bar (#721)

* try to use https://github.com/fyne-io/systray

because of getlantern/systray#191 (comment)

* remove useless dep install, no dependency is required with this fork

see https://github.com/fyne-io/systray#linuxbsd

* update licenses

* manually set license

* the `_cli` binary is no more required since it correctly starts even on systems without a tray bar with this error:
```
systray error: failed to register our icon with the notifier watcher (maybe no tray is running?): The name org.kde.StatusNotifierWatcher was not provided by any .service files

```

* enable static build (macos still requires it)

there are no more dependencies required we can do this
