Expose releasestatus under status.o.o/release.new

Deploy releasestatus site at /srv/static/release and add an alias to
expose that directory under status.o.o/release.new (current deploy
location at /srv/static/release.new was actually not exposed).

That will allow to check everything runs properly before we switch
the main status.o.o/release alias to /srv/static/release.
