Move net/rrdtool to databases/rrdtool.
It's an itch which needs to be scratched: net/rrdtool came from
net/mrtg, which was a good location for it. net/mrtg has later
been moved to net-mgmt/mrtg. net/rrdtool is "Round Robin Database
Tools", therefor it's better if it moves to databases/rrdtool.
Same with net/rrdtool10.
