boot.mk: factor out boot/% from distro.mk

Yes these bits are related to distro/ prefixed images still the overgeneralization in distro.mk didn't pay off but rather hid a bug with the only boot/isolinux in use having no dependency on use/syslinux (which is required). Maybe this will get revisited when we have other kinds of bootable images with other bootloaders (vm/ ones care for themselves as of today).
