Subject: [PATCH] systemd-unit-options: startAt can be a list

OnCalendar entrys can be specified multiple times in a systemd timer, to
make more complex scheduling possible.

Tested by manually checking the timer generated by the following:

    systemd = {
      services.huhu = {
        description = "meh";
        wantedBy = [ "default.target" ];
        serviceConfig.ExecStart = "/bin/sh -c 'printf HUHU!'";
        startAt = [ "*:*:0/30" "*:0/1:15" ];
      };
    };

It prints HUHU to the log at seconds 0, 15 and 30 of each minute.
