netflow mode 32bit: Invalid type 'Q' in unpack at asstatd.pl line 321.

Greetings,

this issue exists on netflow mode only. sflow mode does not exhibit this behavior.

pmacct/nfprobe, quagga & as-stats all run on same physical fresh gentoo/rolling 32bit system.

attaching a wireshark capture:

according to this & this I've made the following patch that at least doesn't let asstatd.pl explode under a 32-bit system.

I believe this is a better patch. It has been successfully tested on a 32bit/IPv4 system.
