[collectd] iptables plugin won't even build in 5.0.3

[Romain Riviere]

Hi,

I already reported that 5.0.2 and earlier had trouble loading the 
iptables plugin on my Gentoo systems.
I just thought I'd give it a try with 5.0.3, and now the plugin won't 
even build :
checking for iptc_handle_t... no
checking for ip6tc_handle_t... no
checking for iptc_init in -liptc... no
(...)
     libiptc . . . . . . . no
(...)
     iptables  . . . . . . no (dependency error)

(also see comments there https://bugs.gentoo.org/show_bug.cgi?id=375733)
