perf trace beauty: Do not try to use the fd->pathname beautifier for bind/connect fd arg

Browse Source 
Doesn't make sense and also we now beautify the sockaddr, which provides
enough info:

  # trace -e close,socket,connec* ssh www.bla.com
  <SNIP>
  close(5)                                = 0
  socket(PF_INET, SOCK_DGRAM|CLOEXEC|NONBLOCK, IPPROTO_IP) = 5
  connect(5, { .family: PF_INET, port: 53, addr: 192.168.44.1 }, 16) = 0
  close(5)                                = 0
  socket(PF_INET, SOCK_STREAM, IPPROTO_TCP) = 5
  ^C#
