netsniff-ng: implement rotating capture files
Add a new option -O, --overwrite which allows to rotate capture files.
The timestamp in the file name is replaced with a number that wraps
around after reaching the specified number of files.
Example usage:
netsniff-ng -s -F 1KiB -O 10 -i eth0 -o /output/folder
Fixes #147
