[perl-Gtk2] In syntax check mode, do not call gtk_init

[Torsten Schönfeld <tsch src gnome org>]

commit 7bb2cc383bba00d98e95b9d371c6f6589c905f31

    In syntax check mode, do not call gtk_init
    
    gtk_init may abort the program (e.g. if DISPLAY is not set), so in
    syntax check mode, only call gtk_init_check even if asked to call
    gtk_init.
    
    Original patch by Alexey Tourbin.
