[racket] Embedded web server in handin-server: Illegal file access

The embedded web server has a check that a file access is OK: either
it's a file that the current user "owns" (in their submission
directory), or it's a solution file or a file in a solution directory
(you can see it from line 203 in "web-status-server.rkt").

But there could also be an error further down that code -- you can't
tell from the (intentionally) generic failure page, or from the web log
file.  Instead, look in the regular handin log, and it should show some
error following a "Status exception".
