Debian: /etc/machine-id is the same across all StarlingX installations with the same BUILD_ID

[Andre Kantek]

Brief Description
-----------------

It was detected that all StarlingX's Debian installations are using the same content in /etc/machine-id, this can't be as this number needs to be a unique value per node, in order to generate valid random MACs. If reused across multiple nodes all SRIOV's VF interfaces on the same
PCI slot will have the same MAC address across the nodes, creating networking problems.

Severity
--------
<Major: System/Feature is usable but degraded>

Steps to Reproduce
------------------
Execute the installation with the same BUILD_ID across several nodes and

Expected Behavior
------------------
The content of /etc/machine-id should be unique per node.

Actual Behavior
----------------
Compare the value of /etc/machine-id, they will be the same.

Reproducibility
---------------
Reproducible

System Configuration
--------------------
Multi-node system

    Debian: clean machine-id generated during installation

    The Debian installations are generating the same machine-id if using
    the same BUILD_ID. This ID is used to generate the value of random
    MACs for SRIOV's VF interfaces, since it is the same across the same
    BUILD_ID the network cards are generating the exact same MAC if the
    NIC is on the same pci-slot across multiple nodes

    This change removes the existing files so each installation's systemd
    can generate an exclusive value

    Test Plan (Debian)
    [PASS] install multiple nodes and verify that each one contains an
            exclusive /etc/machine-id content
    [PASS] reboot node to validate that machine-id does not change on
            subsequent boots
