Minor fixes to PGTK child frames

* src/gtkutil.c (xg_check_special_colors): Handle child frames
correctly.
* src/pgtkfns.c (pgtk_set_child_frame_border_width): Synchronize
code from X.  (bug#55588)
* src/pgtkmenu.c (pgtk_menu_show, pgtk_dialog_show): Allow in
child frames.  There are no problems here.
* src/pgtkterm.c (pgtk_mouse_position): Clean up coding style.
