lighttpd: modernize lighttpd.conf

- remove obsolete modules
- replace mod_compress directives with mod_deflate
- do not enable debug.log-request-handling by default
  (should not be enabled *by default* on any production system,
   especially not an embedded system)
- update TLS syntax for modern recommended use
  (separate files for certificate+chain, and private key)
- remove incorrect comment about server.event-handler
  lighttpd defaults correctly to use kqueue on *BSD systems
- remove ancient config which disables range requests for PDF
  (cargo-culted config from ~15 years ago to address problem
   in then-popular PDF client)
- use recommend config file include syntax
  (more efficient and more deterministic include file ordering)
