Subject: Prefer AppIndicator if DBus interface is available

Starting with Ubuntu 17.10 the interface will be provided by an
extension (shipped by default):

https://github.com/ubuntu/gnome-shell-extension-appindicator

Legacy tray icons have been completely removed in GNOME 3.26. By
checking the interface, this will allow users of other distributions
with GNOME to also use Telegram's indicator with the extension.
