restore disable-nagle logic for connected sockets

Note: Prior to the MPM-as-DSO churn, the following MPMs did not enable this logic:

  WinNT       APR supports no-oping the setsockopt() based on inheriting Nagle from the
              listening socket on this platform, so the new APR call will be a no-op.
  simple      same as WinNT for at least some Unix-y platforms
  BeOS        shrug
