session-helper: Correctly annotate use of Unix FDs in D-Bus API

Browse Source 
This fixes compilation with GLib 2.63’s `gdbus-codegen`, which
automatically enables Unix FD support for D-Bus APIs which use the `h`
type, even if the `org.gtk.GDBus.C.UnixFD` annotation is missing.

By adding the annotation, the generated header whether using
`gdbus-codegen` 2.63 or < 2.63.

This is a slight API break in GLib, but it’s questionable about whether
flatpak should have always had the annotation.
