Debian: clean machine-id generated during installation

Browse Source 
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
