Don't have "set_menus_for_captured_packets()" call

"main_set_for_capture_file()"; it should only deal with menus, not
anything else - and it gets called while the menus are being set up,
which is before the main window has been completely created, so
"main_widgets_show_or_hide()", which is called by
"main_set_for_capture_file()", gets errors trying to show or hide
widgets the pointers to which are null.
