Previously the Docker healthcheck script exited with a bare die(1) / die(2) and no message, so users only saw 'unhealthy' with no clue why. Print an informative reason to STDERR before each failing exit (a connection/HTTP error, or a response that is not a FreshRSS page), without changing the exit codes relied on by Docker HEALTHCHECK.
