Subject: [RFC][PATCH 6/9] gen_initramfs_list.sh: include xattrs

This patch modifies the gen_initramfs_list.sh script to include xattrs
in the initramfs.

Dracut creates the initramfs using the cpio tool on the system, not
the kernel's gen_init_cpio script. The following commands, for example,
would create an initramfs containing xattrs.

dracut -H -f /boot/initramfs-3.XX.0+.img 3.XX.0+ -M --keep \
	--noprelink --nostrip
gen_initramfs_list.sh /var/tmp/initramfs.XXXXXX/ > \
	/var/tmp/initramfs_list.XXXXXX

[Sign files here, if not already signed, using evmctl.]

gen_init_cpio -x /var/tmp/initramfs_list.XXXXXX >  \
	/boot/initramfs-3.XX.0+test.img
