[collectd] tcpconns plugin spews error about missing /proc/net/tcp6

[James Valente]

The tcpconns module tries to read the following two files.

   conn_read_file ("/proc/net/tcp");
   conn_read_file ("/proc/net/tcp6");

My Fedora system does not have the tcp6 file available, and so, the 
following error is reported every 10 seconds to syslog.

   collectd[PID]: tcpconns plugin: fopen (/proc/net/tcp6) failed:
   No such file or directory

Perhaps a missing tcp6 file should be a warning, rather than an error?

   ERROR ("tcpconns plugin: fopen (%s) failed: %s",
