[PATCH bpf-next v2 6/7] selftest/bpf/benchs: print less if the quiet option is set

[Anton Protopopov <aspsk@xxxxxxxxxxxxx>]

The bench utility will print

    Setting up benchmark '<bench-name>'...
    Benchmark '<bench-name>' started.

on startup to stdout. Suppress this output if --quiet option if given. This
makes it simpler to parse benchmark output by a script.
