hgweb: map Abort to 403 error to report inaccessible path for example

Abort is so common in our codebase. We could instead introduce a dedicated
type for path auditing errors, but we'll probably have to catch error.Abort
anyway.

As you can see, an abort message may include a full path to the repository,
which might be considered information leak. If that matters, we should hide
the message and send it to the server log instead.
