David Marchand 7404d25ea7 system-dpdk: Test with mlx5 devices. 
The DPDK unit test only runs if vfio or igb_uio kernel modules are loaded:
on systems with only mlx5, this test is always skipped.

Besides, the test tries to grab the first device listed by dpdk-devbind.py,
regardless of the PCI device status regarding kmod binding.

Remove dependency on this DPDK script and use a minimal script that
reads PCI sysfs.

This script is not perfect, as one can imagine PCI devices bound to
vfio-pci for virtual machines.
Plus, this script only tries to take over vfio-pci devices. mlx5 devices
can't be taken over blindly as it could mean losing connectivity to the
machine if the netdev was in use for this system.

For those two reasons, add a new environment variable DPDK_PCI_ADDR for
testers to select the PCI device of their liking.
For consistency and grep, the temporary file PCI_ADDR is renamed
to DPDK_PCI_ADDR.
