Makoto Kato 18c5223126 Bug 1151753 - Set program class name when not using --class command line option. r=karlt
GTK bug: https://bugzilla.gnome.org/show_bug.cgi?id=747634

Before 3.16.3, GDK cannot override classname by --class command line option
when program uses gdk_set_program_class().  So if 3.16.3+, we should call
gdk_set_program_class() to set program class name of default.
