This commit adds a test prog for vprintk which confirms that: * bpf_trace_vprintk is writing to /sys/kernel/debug/tracing/trace_pipe * __bpf_vprintk macro works as expected * >3 args are printed * bpf_printk w/ 0 format args compiles * bpf_trace_vprintk call w/ a fmt specifier but NULL fmt data fails Approach and code are borrowed from trace_printk test.
