Avoid sending the Referer header when redirecting the view URL request

[llucax]

For privacy reasons, we should stay stealth to the target websites, so they can't track if users were using this service or not.

Does it include removal of line no 88 in fetch function in src/url_info.rs or it includes more than that?

Not really, that would sort of make the noclickd server more stealth, but it shouldn't affect the users privacy. This is about using a referrer policy when doing the redirect for the user visiting the no-click link.
