Domain without available wwsympa_url parameter should deny web access

In Sub _merge_msg Content-Disposition: attachement in multipart-messages will be copied without modification.

Let the default of `--with-lockdir` be `/var/lock/subsys` always

WWSympa: Deny access if wwsympa_url parameter is unavailable for a domain (neither in robot.conf and sympa.conf).

[-change] Rename nginx-{wwsympa,sympasoap}.service files to {wwsympa,sympasoap}.service: It may be used by other httpd.

This directory was originally prepared for [upstart](http://upstart.ubuntu.com/) which has been adopted by Fedora/RHEL, Debian/Ubuntu etc. (On Systemd, this directory is included in `tmpfiles.d/legacy.conf` for compatibility with "legacy" systems).
Thus, the default value of this option should not depend on `--prefix` option of each application.
