[meta-initramfs][PATCH 1/2] initramfs-kexecboot-image: support cases where machines override IMAGE_FSTYPES

["Andrea Adami" <andrea.adami@gmail.com>]

test case: zaurus.inc

IMAGE_FSTYPES ?= "tar.gz jffs2 jffs2.sum ubi ubifs"
IMAGE_FSTYPES_collie ?= "tar.gz jffs2 jffs2.sum"
INITRAMFS_FSTYPES ?= "cpio.gz cpio.xz"

The last assignment IMAGE_FSTYPES = "${INITRAMFS_FSTYPES}" did in fact
reset the value to IMAGE_FSTYPES_collie, thus not producing cpio.gz / cpio.xz.
