xdp-tools: disable stack protector for BPF programs

When building xdp-tools with CONFIG_USE_LLVM_HOST=y, on a host that
enabled stack protector by default in Clang, compilation fails with the
following error:

    CLANG    xdp-dispatcher.o
clang-16: error: ignoring '-fstack-protector-strong' option as it is not currently supported for target 'bpfeb' [-Werror,-Woption-ignored]

Add -fno-stack-protector to BPF_CFLAGS to fix this.
