xdp-tools: add package

xdp-tools - Library and utilities for use with the eXpress Data Path:
Fast Programmable Packet Processing in the Operating System Kernel

 * libxdp: library for attaching XDP programs and using AF_XDP sockets
 * xdp-filter: a simple XDP-powered packet filter
 * xdp-loader: an XDP program loader
 * xdpdump: tool for capturing packets at the XDP layer

Thanks to Nick @PolynomialDivision Hainke for testing and fixing!

+define Package/xdp-filter/description
+xdp-filter is a packet filtering utility powered by XDP. It is deliberately
+simple and so does not have the same matching capabilities as, e.g.,
+netfilter. Instead, thanks to XDP, it can achieve very high drop rates:
+tens of millions of packets per second on a single CPU core.

+define Package/xdp-loader/description
+xdp-loader is a simple loader for XDP programs with support for attaching
+multiple programs to the same interface. To achieve this it exposes the same
+load and unload semantics exposed by the libxdp library.
