Fix sysroot_ld_path.sh to correctly process the included configs.

The $included_files var contains a list of paths relative to the sysroot.
However calling `ls $included_files` gives us a list of paths relative to the host system root, which is obviously wrong. We need to do `ls $root$included_files` instead.
