[Bug-wget] Docs missing info on ca_directory and ca_certfile

[Jeffrey Walton]

The sample wgetrc is missing info on ca_directory . Also see
https://www.gnu.org/software/wget/manual/html_node/Sample-Wgetrc.html.

I also cannot figure out how to tell Wget to use cacert.pem. I've
tried ca_cert, ca_certs and ca_certfile but it produces:

    wget: Unknown command ‘ca_file’ in /opt/bootstrap/etc/wgetrc at line 141
    Parsing system wgetrc file failed.

Any information on configuring cacerts.pem at build time would be welcomed.
