run(): Convert `fastcgi::Request` to `http::Request`

Build a new `http::Request` from the `fastcgi::Request` and pass it into
the closure.

Can't move `req`, so needed to change the `from` converter to take a
reference.

Update the example code to append the `http::Request` to a file for
debugging and inspection.
