Test 30 - "root=dhcp" fails on Debian

[bdrung]

https://github.com/dracutdevs/dracut/blob/master/test/TEST-30-ISCSI/test.sh#L81 hangs (no output for minutes) when running on a Debian container:

$ podman run --rm -it --cap-add=SYS_PTRACE --user 0 -v /dev:/dev -v ./:/dracut:z ghcr.io/dracutdevs/debian:latest bash -l
$ dpkg --purge multipath-tools
$ cd /dracut && ./configure && make -j8 && cd test
$ make V=1 KVERSION="$(cd /lib/modules; ls -1 | tail -1)" TESTS="30" clean check

Test 30 seem to be passing both on Fedora and Arch (log from those containers can be used as reference).

dracut[I]: *** Including module: iscsi ***
Failed to enable unit, unit iscsiuio.socket does not exist.

Test 35. seems to have a similar issue as Test 30.

In the Fedora and Arch test container /usr/lib/systemd/system/iscsiuio.socket file exists. In the Debian and Ubuntu test container it does not. Installing the iscsiuio might be required for in the Debian and Ubuntu test container, but even installing that package does not seems to install iscsiuio.socket file.
