Make Fl_Sys_Menu_Bar::update() public and cross-platform.

It was before protected and Mac OS-specific.
This allows to call it after direct modification of menu items.

  \n To use this class, just replace Fl_Menu_Bar by Fl_Sys_Menu_Bar, and, on the Mac platform,
  a system menu at the top of the screen will be available. This menu will match an array
  of Fl_Menu_Item's exactly as with standard FLTK menus.

+ Changes to the menu state are immediately visible in the menubar when they are made
+ using member functions of the Fl_Sys_Menu_Bar class. Other changes (e.g., by a call to
+ Fl_Menu_Item::set()) should be followed by a call to Fl_Sys_Menu_Bar::update() to be
