[fix] Force Google old UI with a new user agent

[unixfox]

Google started to serve the new UI (that Searx can't parse) on Internet Explorer (all versions) so found out that by providing a very old version of Safari as a user agent Google let me load the old UI.

Why did I choose this very specific user agent? I wanted to use a quite common agent to avoid Google blocking it so picked this one which according to whatismybrowser.com is very common:

https://developers.whatismybrowser.com/useragents/explore/software_name/safari/1

Fixes #1748
Fixes #1704

Tested with search query "!go foofoo" before and after patched my forked branch dm-cloud.

Works! / Thanks a lot!

Just a thought for later: What about trying the Lynx/Links user agents later, for when this happens again?

[unixfox]

@virtadpt I tried multiple user agent from this list: https://developers.whatismybrowser.com/useragents/explore/software_name/lynx/ but none of them let me load the old Google UI, so I don't think that's the good user agent for that.
Mainly because Lynx is just not that popular for Google to take into account. Whereas with Safari it's still a browser quite popular.

IIRC, Google Search works fine in Lynx/Links.

That doesn't mean it's loading the old UI, Google has developed a special version of their new UI specially for the old browsers like IE and it's working fine even better than the old UI.
