send-email: --smtp-ssl-cert-path takes an argument

35035bb (send-email: be explicit with SSL certificate verification,
2013-07-18) forgot to specify that --smtp-ssl-cert-path takes a string
argument.  This means that the option could not actually be used as
intended.  Presumably noone noticed because it's much easier to set it
through configs anyway.

Add the required "=s".
