[aur-general] Packages with libpcap dependency need a rebuild

Soon (today or tomorrow), libpcap 1.0.0 will move to core. All community packages depending on libpcap will need a rebuild (iftop is among them, no idea if there are more). The rebuilds probably won't be necessary for each version anymore, as the libpcap.so has no a sane SONAME (.so.1) instead of having the whole version (including the minor) as SONAME.
