traffic_packets: add windows instructions for ldap 0 simple bind

To run packet_ldap_0 simple bind test against Windows, we need to
install CA on Windows with following PowerShell commands:

  Install-windowsfeature ADCS-Cert-Authority
  Install-AdcsCertificationAuthority -CAType EnterpriseRootCA
  Restart-Computer

Otherwise we will get `NT_STATUS_CONNECTION_RESET` error.

Didn't change any code, just add above instructions in comment.
