Subject: elflink: Do clear screen even if we have no pDraw_Menu method
X-Git-Tag: syslinux-5.00-pre1~85

elflink: Do clear screen even if we have no pDraw_Menu method

Do clear screen even if we have no pDraw_Menu method, since user
may work in CLI mode and want to clear screen by pressing 'Ctrl-L'.
