fix(dracut-install): continue parsing if ldd prints "cannot be preloa…

…ded"

When /etc/ld.so.preload contains a non-existing library, `ldd` prints the
following output:

```
> ldd /usr/lib64/libfido2.so.1.12.0
ERROR: ld.so: object '/usr/lib64/libfoo.so' from /etc/ld.so.preload cannot be preloaded (cannot open shared object file): ignored.

> echo $?
0
ERROR: ld.so: object '/usr/lib64/libfoo.so' from /etc/ld.so.preload cannot be preloaded (cannot open shared object file): ignored.
```

If `dracut-install` stops parsing the `ldd` output, the initrd will not contain
all the required dependencies.
