dracut: fix boot on non-zfs-root systems
Simply prevent overwriting root until it needs to be overwritten. Dracut could change this value before this module is called, but won't change the kernel command line. Reviewed-by: Andrew J. Hesford <ajh@sideband.org> Signed-off-by: Toyam Cox <vaelatern@voidlinux.org> Closes #13592
