Ayatana indicators
<!-- Uncomment relevant sections and delete options which are not applicable -->

Continuation of #35135

`libappindicator` hasn't seen a release since 2012 (more than 10 years!)
Debian has removed it in buster and switched to [libayatana-appindicator](https://ayatanaindicators.github.io/).
This PR tries to replace `libappindicator` with `libayatana-appindicator`.
