Subject: [PATCH] always unpack initrd to relative paths

If cpio archive contains absolute filenames, files are unpacked
relative to host root '/', not 'ramdisk' directory.
If abootimg-unpack-initrd is run as root, that could break host system
and make it unbootable by overwriting important system files.
