net/ruby-ruby_smb: update to 2.0.1

Update ruby-ruby_smb to 2.0.1.

* store server time values and GUDI

* Fix issues with Mac OS X SMB server

  - Set the unicode flag on the Negotiate SMB Header request
  - Check if the Socket is closed before calling IO.select
  - Improve Socket#recv_packet exception handling

* Update related to Win8 errors

  - Change :encryption_required parameter name to a more meaningful name
    according to the context: :session_encrypt_data and
    :tree_connect_encrypt_data.
  - #can_be_encrypted? now returns false with SMB1 packet.
  - Improve exception handling in #recv_encrypt in case an encryption error
    occurs on the server (this will help in detecting the unpatched Win8
    bug).
  - Only enable session encryption if the server supports it. This only
    applies if session_encrypt_data was originally set (forced). If it is
    not set, session encryption will stay disabled even if the server
    supports encryption.

* More fixes
  - Remove the `OEM` flag when initializing the `Net::NTLM::Client`.
    Unicode is the default now and `Net::NTLM::Client` does not handle OEM
    string correctly.
  - Improve error message when an SMB1 `NtCreateAndxResponse` is received
    without extended information.
