[Lazarus] workaround for trayicon.hint is ok with Manjaro XFCE

[John Landmesser]

if i use this script to start my application

> #! /bin/bash
> # Lazarus App mit gesetzter Umgebungsvariablen starten
> # APPIND Debug : User choosing to use Traditional SysTray
> export LAZUSEAPPIND=NO
> /run/media/john1/ntfs1/PROJEKTE/Lazarus/Sanduhr/Sanduhr


TrayIcon.hint works again :-)

But it's easier to set

> LCLWidgetType:=qt5
  in project settings.

But good to know this alternative!!
