xdp-tools: fix compilation wrongly using host header
Currently it's needed to have gcc-multilib on the host to correctly
compile xdp-tools. This is wrong and means that we are using host header
to compile a tool.

By some searching in how the makefile works it was discovered that
BPF_CFLAGS were not used and required to be appended to config.mk

Only one single header was added but we should include each BPF_CFLAGS
from bpf.mk. To make this some patching to bpf-header were required and
some patches to xdp-tools were required.
Also it's needed to pass the correct target to BPF_CFLAGS.

With the following changes xdp-tools can correctly compile with each
header from bpf-headers and should not use any host header.
