app-containers/lxd: add 4.0.9

 - inherit go-module.eclass; upstream uses go.mod now,
 - new documentation offered by upstream, e.g. a handy cheatsheet,
 - openrc init file and systemd service file now manages the log
   directory (#817287),
 - virtfs-proxy-helper bin path isn't hardcoded anymore (#798924),
 - -Werror patch turned into sed for easier maintainability.

Bug: https://bugs.gentoo.org/798924
Closes: https://bugs.gentoo.org/817287
