openbsd: update relayd and httpd configuration files

Browse source 
* httpd: use proper server names
* httpd: add example of a very basic static website along with Pleroma
* httpd: let Pleroma serve robots.txt
* relayd: add example of forwarding to a basic httpd website
* relayd: remove appended response headers (most of them already served
  by Pleroma anyway)
* relayd: add comments about hosting Pleroma on subdomains
* relayd: reject request that don't belong to any forward
* relayd: add example of hosting media uploads on subdomain
* relayd: change forward timeout check to something sane that actually
  works
