httpd: always forward the 'Authorization' header

On some Apache HTTPD setups where the CGI/FastCGI mode is used, the HTTP header
containing the JWT token is not forwarded, which results in the following error
when attempting to use the REST API:

  "401 Not authorized: JWT token not provided"

This patch allows forwarding the 'Authorization' header. An alternative would
be to use the `CGIPassAuth` directive to allow all authorization headers to be
forwarded.
