hgweb: add compatibility code for old templates
Up to changeset
3340aa5a64f7, HTTP headers were expected to be embedded
in the "headers" template. Since that changeset, the content-type is
supposed to be defined as the "mimetype" template in the map file.
This changeset makes sure the old templates still work.
