xdp-tools: add recipe

Import xdp-tools recipe from meta-dpdk to meta-oe.

xdp-tools provides a set of utilities and helpers for working
with XDP (eXpress Data Path) and eBPF-based packet processing
in the Linux networking stack.

Although currently available in meta-dpdk, xdp-tools is a
standalone utility with no direct dependency on DPDK, and is
generally useful for networking and XDP-based workflows.
Adding it to meta-oe makes it available without requiring
the meta-dpdk layer.

+Subject: [PATCH] configure: skip toolchain checks
+
+Current logic fetch full command line along with the tool. i.e
+gcc -m64 -march=skylake -mtune=generic ...
+
+Which throws ERROR: Cannot find tool -m64
+
+So need to re-write for loop, so it can work in cross-compilation
+environment too.
