Flatpak doesn't allow to own random name with PID. Even after adding
such a permission into manifest, all flatpaked apps have PID 2, so only
one Qt application at a time can have tray icon.
Even though unique name is a part of the spec, no tray hosts really
check it and SNI implementations without unique name run just fine
inside and outside of Flatpak.
This fixes the inability of Qt applications to have tray icon in Flatpak
outside of KDE.
Pick-to: 6.0 6.1 5.15
