DPDK support check broken with OVS-DPDK on Debian

[Thales Elero Cervi]

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

For data-neetwork interfaces, sysinv currently relies on query_pci_id script [1], that relies on the provided dpdk-pmdinfo.py script, to check if a NIC supports DPDK. This script needs an ELF file to check DPDK compatibility against, currently it is using the ovs-dpdk built binary: /usr/sbin/ovs-vswitchd

On Debian though, this script is no longer able to correctly check DPDK compatibility since it always fails to check even supported devices (vendor+device).

It is probably a build issue introduced when Openvswitch package was ported to Debian

Severity
--------
Critical: ovs-dpdk configuration is not usable due to the defect

Steps to Reproduce
------------------
* List host available ports: system host-port-list controller-0
* Get one of the data-networks PCI ID
* From /sys/bus/pci/devices/ get both the VendorID and DeviceID for that port
* Make sure this NIC is officially supported by the current OVS-DPDK version
* Manually execute the script "query_pci_id -v 0xabcd -d 0x1234"

Expected Behavior
------------------
Given that the NIC is officially supported by the current OVS-DPDK version, the script must print: "Vendor ID: 0xabcd Device ID: 0x1234 is supported"

Actual Behavior
----------------
Even when the NIC is officially supported by the current OVS-DPDK version, the script prints: "Vendor ID: 0xabcd Device ID: 0x1234 is not supported"

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

Also affected by this, in my installation that was made from starlingx-intel-x86-64-20230211131909-cd.iso dpdk-pmdinfo.py was missing from /usr/share/openvswitch/scripts/ where it is supposed to be according to query_pci_id.

Fix was proposed but a complete OVS-DPDK deployment will only be possible after [1] is fixed.
