[OE-core] [v3 PATCH 4/9] syslinux.bbclass, syslinux: Update to syslinux 6.01

[Jason Wessel]

A newer version of syslinux is required for an EFI enabled isohybrid.
This is used for the the capability to generate 3 types of ISO images,
all of which can be booted off a USB device or HDD if copied with dd.

1) PC BIOS only ISO
2) EFI only ISO
3) EFI + PC BIOS ISO

The syslinux.bbclass required a minor tweak because a few .c32
libraries require dynamic loading from the created media as of
syslinux 5 and up.  This was a good time to also fix the
duplication of the AUTO_SYSLINUXMENU block.

[YOCTO #4100]
