Sets the name of the program. This name should not be localized,
in contrast to g_set_application_name().
If you are using #GApplication the program name is set in
g_application_run(). In case of GDK or GTK+ it is set in
gdk_init(), which is called by gtk_init() and the
#GtkApplication::startup handler. The program name is found by
taking the last component of @argv[0].
Note that for thread-safety reasons this function can only be called once.
