[lukashino]

Redmine ticket: https://redmine.openinfosecfoundation.org/issues/6927 Follow-up of: #10838

Describe changes: v3

• comments from Philippe
• I left TAILQ_INIT in the finalize/cleanup functions - all elements of the arrays are cleaned but not the base pointer of the array itself. TAILQ_* functions don't offer reset function but TAILQ_INIT provides the desired outcome
• moved guards around - per Philippe's suggestions

v2

• added a FatalError check on the number of LiveDevices
• changed #if HAVE_DPDK to #if defined(HAVE_DPDK) && defined(UNITTESTS)
• enabled unit tests in the Github workflow runs on Ubuntu and Fedora tasks

v1

• function-guarded variable
• fix the CPU exclude logic
• add DPDK unit tests
