LibWeb+WebContent: Do not reference-count file request objects

Browse source 
There is currently a memory leak with these file request objects due to
the callback on_file_request_finish referencing itself in its capture
list. This object does not need to be reference counted or allocated on
the heap. It is only ever stored in a HashMap until a response is
received from the browser, and it is not shared.
