    Glib 2.62+ requires gdbus.exe for dbus-related apis
    
    Usage of rundll32 was replaced by usage of gdbus.exe during fixing
    https://gitlab.gnome.org/GNOME/glib/issues/1566
    moved form meld's bug https://gitlab.gnome.org/GNOME/meld/issues/220
    
    Since meld msi's on gitlab are built with rolling-release msys2
    that already upgraded to glib 2.62
    the gdbus.exe binary must be included in meld distribution.
    
    Without this meld distribution built on current msys just silenetly fails
    to do dbus communications (each process behaves indepently).
    
    This patch does NOT break building meld distribution
    with earlier versions of msys2: the gdbus.exe binary do present in
    versions earlier to 2.62 (just not used for running session dbus)
