Missing semicolon in example configuration files

[jblang]

This commented line is missing a semicolon: https://github.com/vouch/vouch-proxy/blob/master/examples/nginx/single-file/nginx_with_vouch_single_server.conf#L84

I uncommented it because I wasn't seeing X-Vouch-User in my headers but then nginx refused to start with a very unhelpful error message:

nginx: [emerg] invalid number of arguments in "auth_request_set" directive in /etc/nginx/conf.d/default.conf:58

It took me a lot of head scratching before I noticed the semicolon was missing. It's actually missing in several other examples and the README:

~/repos/vouch-proxy$ git grep -n upstream_http_x_vouch_user | grep '[^;]$'
README.md:144:      #    auth_request_set $auth_resp_x_vouch_user $upstream_http_x_vouch_user

Thanks for fixing, but you missed the one on line 144 the readme.
