[OE-core] [PATCH 8/8] boot-directdisk.bbclass: use rootfs UUID by default

[Patrick Ohly]

This changes the default SYSLINUX_ROOTFS such that the rootfs is no
longer expected under a fixed device path. Instead, the UUID is used
to find it. This makes the resulting .hdddirect (and thus also the
vdi/vdmk/qcow2 images derived from that) more flexible.
