Enable forwarded headers by default instead of relying on environment variable

System.getenv("HTTP_FORWARDEDHEADERS_ENABLED") returns null in Mizuho's
production environment (JBoss behind reverse proxy) even though the variable
is correctly set. Since x-forwarded-for header contains the real client IP,
the fix is to enable forwarded headers by default, restoring v16 behavior
and removing the need to configure an environment variable.
