ap_http_header_filter: avoid double encoding of output headers in traces.

When output headers are logged (TRACE4) in send_all_header_fields(), we don't
need to explicitely ap_escape_logitem() them since ap_log_rerror() takes care
of log files escaping already.

Otherwise, characters like '"' are unncesseralily encoded, and '\\' is doubly
encoded (including for controls).
