doc: Fix incorrect openssl option

The openssl command for displaying the DN of a client certificate was
using --subject and not the single-dash option -subject. While recent
versions of openssl handles double dash options,  earlier does not so
fix by using just -subject  (which is per the openssl documentation).

Backpatch to v14 where this was introduced.

format. To see the <literal>DN</literal> of a client certificate
in this format, do
<programlisting>
openssl x509 -in myclient.crt -noout --subject -nameopt RFC2253 | sed "s/^subject=//"
openssl x509 -in myclient.crt -noout -subject -nameopt RFC2253 | sed "s/^subject=//"
</programlisting>
Care needs to be taken when using this option, especially when using
regular expression matching against the <literal>DN</literal>.
