  1. util: Use bpf_trace_vprintk() directly in sample detection program 

    The dummy program we use to feature detect for xdp-sample doesn't compile
on old versions of libbpf that don't have the macro feature that selects
bpf_trace_vprintk() if the number of args exceeds what bpf_trace_printk()
supports. To get around this, just use the bpf_trace_vprintk() helper
directly, which should hopefully work on old libbpf versions as well.
