check_curl: abort redir if location is not found

Browse source 
This commit changes the behaviour of check_curl slightly.
Previously when the redirection method was set to the old 'check_http'
style redirection and there was no "location" header in the original
answer 'check_curl' segfaulted.
Now, at least it dies properly with a message.
