check_http: Abort invalid SSL w/ error

If a SSL connection cannot be established, check_http bailed out with a
die function call with a NULL fmt string. This adds a more meaningful
message.

The motivation for this patch was to get everything from the OpenBSD
ports upstream. It seems like in the old days, this would have resulted
in a segfault.

However, even if "die" now checks for NULL, a human readable error is
nice to have.
