    xdp-tools: fix compilation when bpftool is installed
    
    Currently, xdp-tools doesn't compile on build systems where
    bpftool is installed because additional tools and BPF programs
    will be compiled then, which results in build errors.
    
    This commit disables the compilation of those bpftool-dependent tools.
