Subject: bootimg: Pull syslinux specific bits into syslinux.bbclass

Working towards a more generic bootimg.bbclass, pull out all
syslinux specific bits and let syslinux.bbclass manage them
directly. This introduces no functional changes to the images
constructed and the behavior remains unchanged.
