Bug/Problem was incoming with IPv6 on earlier versions FreeBSD

The problem seems to be that the author is passing the size of sockaddr_storage to sendmsg() in the header rather then the size of the actual sockaddr_in/in6 struct contained within. I think this creates a size mismatch with the msg_name field that FreeBSD 13.1 checks for resulting in the EINVAL return code from the sendmsg() call. This patch will get it going again, though I am not sure if it is complete, the receive side may need some changes too, but it seems to work:

The patch also changes ttl to an int instead of an unsigned char which fixes the setsockopt() call for the ttl in FreeBSD. I have not tested if this breaks Linux at all.

I tested this PR on Linux Kernel 5.17.9 and I had no issues compiling check_icmp or running a test ping with v4 and v6.

Thanks for the patch and for testing it. I'll try to get this fix into the next release.
