[dpdk-dev] [DPDK_KMODS v4] linux/igb_uio: add Makefile to build the kernel module

[Hariprasad Govindharajan]

With DPDK 20.11 release, the igb_uio module is no more part of DPDK.
There are use cases where this module is required, for example while
testing the virtual ports in OvS, the virtual ports are bound to
igb_uio module inside a VM. So, this patch provides a Makefile
which can be used to build this module and use as needed.

Before building this module, the user is expected to build the
DPDK using meson build system and make sure that the required
libraries are installed in the path /usr/local
