[syslinux] disable MBR install for images using SysLinux 4.x with a >4 GB file

Browse source 
* The presence of a > 4 GB file forces the use of NTFS which is incompatible with
  SysLinux 4.x or earlier. As such, if an image uses SysLinux only, there's no
  point in enabling MBR as SysLinux won't boot.
* Required for ISOs such as securityonion-2.0.1-rc1.iso.
