After running check-url.pl on couple of Koha instances i noticed that every
single URL from books.google.com came back with 401 Unauthorized error, even
though the URLs were very much alive.

I have changed the http user-agent, and now it works OK.

Here is my fix:

koha/koha.git/misc/cronjobs# diff check-url.pl check-url-calyx.pl 
88c88
<     my ($class, $timeout) = @_;
---
>     my ($class, $timeout, $agent) = @_;
91a92
>     $uagent->agent( $agent) if $agent;
159a161
> my $agent     = '';
166a169
>     'agent=s'    => \$agent,
187c190
<     my $checker = C4::URL::Checker->new($timeout);
---
>     my $checker = C4::URL::Checker->new($timeout,$agent);
246c249
< =item check-url.pl [--verbose|--help] [--host=http://default.tld] 
---
> =item check-url.pl [--verbose|--help|--agent] [--host=http://default.tld] 
266a270,275
> =item B<--agent>
> 
> Change default libwww user-agent string to custom.
> Some sites does not like libwww user agent and so check-url gives
> error even if the site works from browser.
>  

Please note that i am not a perl developer. The patch has been tested on
several Koha installs, but there might be a nicer solution out there.
