Client: Make plugin helper override directory mode u=rwx,go=

Even though it currently is not used, a local administrator might use
setuid (or setcap) executables as plugin helpers.  Thus, the plugin
helper override directory (/etc/mandos/plugin-helpers) must be
secured, just as the plugin override directory (/etc/mandos/plugins.d)
is.

* Makefile (install-client-nokey): Install plugin-helper directory as
                                   mode u=rwx.
* debian/mandos-client.lintian-overrides: Do not warn about
                               permissions on plugin helper directory.
* debian/mandos-client.postinst (configure): Fix permissions on plugin
  helper local override directory (/etc/mandos/plugin-helpers), but
  only if not listed by "dpkg-statoverride".
