fix(env) change file logs to stdout/stderr

[rainest]

What this PR does / why we need it:

Default all logs to stderr/stdout or off. The Docker distributions hit most of these already, so some of these settings are redundant, but there are several that we never changed at build time.

Special notes for your reviewer:

Before:

bash-5.1$ grep access_log .kong_env
portal_api_access_log = /dev/stdout
proxy_stream_access_log = logs/access.log basic
portal_gui_access_log = logs/portal_gui_access.log
admin_gui_access_log = /dev/stdout
proxy_access_log = /dev/stdout
admin_access_log = /dev/stdout
status_access_log = off

bash-5.1$ grep error_log .kong_env 
portal_api_error_log = /dev/stderr
admin_gui_error_log = /dev/stderr
status_error_log = logs/status_error.log
proxy_stream_error_log = logs/error.log
admin_error_log = /dev/stderr
proxy_error_log = /dev/stderr
portal_gui_error_log = logs/portal_gui_error.log

After:

bash-5.1$ grep access_log .kong_env
portal_api_access_log = /dev/stdout
proxy_access_log = /dev/stdout
proxy_stream_access_log = /dev/stdout basic
status_access_log = off
portal_gui_access_log = /dev/stdout
admin_gui_access_log = /dev/stdout
admin_access_log = /dev/stdout

bash-5.1$ grep error_log .kong_env
portal_api_error_log = /dev/stderr
proxy_stream_error_log = /dev/stderr
status_error_log = /dev/stderr
admin_gui_error_log = /dev/stderr
portal_gui_error_log = /dev/stderr
admin_error_log = /dev/stderr
proxy_error_log = /dev/stderr
