[pygobject] Use PyLong_Type.tp_new for GLib.Pid

[Simon Feltman <sfeltman src gnome org>]

commit 2d203b7529c95ba4461a5a6d4c6b67169fabc4cf

    Use PyLong_Type.tp_new for GLib.Pid
    
    For GLib.Pid the original implementation for __new__ needs to be used,
    as it is able to initialize the integer correctly.
