check_icmp: use packet reception time to compute rtt (#1232)

Currently, check_icmp uses processing time to compute rtt. This can lead to
invalid values when the machine is heavily loaded. The patch I propose uses
the SO_TIMESTAMP feature of setsockopt to use the kernel reception time
instead. You can merge this Pull Request by running:

git pull master

Or you can view, comment on it, or merge it online at:
