Use "struct sockaddr_storage" instead of a union in mandos-client.

Apparently using struct sockaddr_storage the way POSIX intended is
incompatible with strict aliasing, so turn that off in the Makefile.

* plugins.d/mandos-client.c (start_mandos_communication): Change "to"
                                                          from a union
                                                          to a struct
                                                          sockaddr_storage.
* Makefile (OPTIMIZE): Add "-fno-strict-aliasing".
