    flatpak: Better pin down the PCSX commit hash
    
    Theoretically this should have worked, but it requires a very new
    flatpak-builder, whereas using "branch" works with old and new versions.
    
    This was a problem for us because the GNOME build machines currently
    have an older flatpak-builder installed, and we really want to pin PCSX
    now.
