uhttpd: added uhttpd.docroot
Passes the document-root to the Lua handler by placing it in uhttpd.docroot. It could alternatively be placed in env.DOCUMENT_ROOT which would more closely resemble the CGI protocol; but would mean that it is not available at the time when the handler-chunk is loaded but rather not until the handler is called, without any code savings.
