fix(dracut): library directory creation in --kernel-only

Create a initrd with `--kernel-only`. For example:

```
./configure
make
./dracut.sh -l --kernel-only -m kernel-modules -d "ext4 sd_mod" -f $(pwd)/test --keep
```

The resulting has directories with spaces:

```
$ ls -l /var/tmp/dracut.dS9eq2i/initramfs
total 0
drwxrwxr-x 3 root root 60 Aug 13 23:36 ' '
lrwxrwxrwx 1 root root  7 Aug 13 23:36  lib -> usr/lib
drwxr-xr-x 3 root root 60 Aug 13 23:36  usr

```

Do not quote `libdirs` when iterating over it since it contains a
space-separated list of library directories.
