+ 去除CGI传进来的script前缀

Symptom: lighttpd 调用fastcgi时, 会将script name也一起传进来,
比如 script name: /django-fastcgi,  path: /home/
url.rewrite-once = (
    "^(/static/.*)$" => "$1",
    "^/favicon\.ico$" => "/static/favicon.ico",
    "^(/.*)$" => "/django_fastcgi$1",
)
传递给Django时候, 会被解析成: /django-fastcgi/home/
