[collectd] tcpconns plugin: Trouble under *BSD?

I haven't run collectd on *BSD yet, but I can confirm this is the case.
The sigar library has an api that provides the same data as the tcpconns
plugin, the impls are likely similar.
This was the initial OpenBSD port:
conn.local_port  = ntohs(inpcb.inp_lport);
conn.remote_port = ntohs(inpcb.inp_fport);

When we ported to NetBSD the same code applies.  And, the #else for
FreeBSD + Darwin also converts via ntohs.  Btw one of these days I'll
get around to patching collectd to make use of libsigar :)
