daemon: refresh before forking

This means we always load the PSGI server code early for
-httpd.  This may make things less compatible with existing
PSGI/Plack apps, but we prioritize our httpd for the uses
of public-inbox itself, first.

And any existing PSGI/Plack app which wants to may adapt
themselves to being preload-friendly.
