[PATCH 02/11] tcp: Change SO_PEEK_OFF support message to debug()

[Stefano Brivio <sbrivio@redhat.com>]

This:

  $ ./pasta
  SO_PEEK_OFF not supported
  #

is a bit annoying, and might trick users who face other issues into
thinking that SO_PEEK_OFF not being supported on a given kernel is
an actual issue.

Even if SO_PEEK_OFF is supported by the kernel, that would be the
only message displayed there, with default options, which looks a bit
out of context.

Switch that to debug(): now that Podman users can pass --debug too, we
can find out quickly if it's supported or not, if SO_PEEK_OFF usage is
suspected of causing any issue.
