[dracut] avoid 100s delay with rpm-ostree cliwrap

When calling dracut on an rpm-ostree based system
with cliwrap enabled you get the following message:
```
This system is rpm-ostree based; initramfs handling is
integrated with the underlying ostree transaction mechanism.
Use `rpm-ostree initramfs` to control client-side initramfs generation.
rpm-ostree: Note: This system is image (rpm-ostree) based.
rpm-ostree: Dropping privileges as `dracut` was executed with not "known safe" arguments.
rpm-ostree: You may invoke the real `dracut` binary in `/usr/libexec/rpm-ostree/wrapped/dracut`.
rpm-ostree: Continuing execution in 5 seconds.
```

Calling `/usr/libexec/rpm-ostree/wrapped/dracut --print-cmdline` is
still slow because it calls rpm multiple times which is also a wrapped
cli. Call dracut with the env variable RPMOSTREE_CLIWRAP_SKIP to avoid
the 5s waits. This is safe because we only use read only commands.

With rpm-ostree v2024.4 `rpm --eval` is marked as safe, so we don't
have the 5s wait anymore for rpm calls
(coreos/rpm-ostree#4835)
