[OE-core] [meta-oe][PATCH] wic: isoimage-isohybrid: check for syslinux-native

[Mihaly Varga]

.iso image creation fails if during the image creation syslinux
is baked and syslinux-native is not.

Added new check to verify if both syslinux and syslinux-native
are baked and bake them if these are not installed.
