check_curl: Documentation for --certificate, --cookie-jar

>From the mere help output for -C / --certificate, I was confused about
what its two integer parameters do. Unfortunately, I also missed out on
the explaining examples later. Since I like to have basic documentation
for each flag, I tried to make the arguments as short as possible.

The other fix was one hyphen too many for the --cookie-jar option.
