exploit/windows/local/persistence_service lies about supported session types

[bcoles]

modules/exploits/windows/local/persistence_service.rb

This is a lie:

      'SessionTypes'  => [ 'meterpreter', 'shell'],

Due to:

  # Function for writing executable to target host
  # Code from post/windows/manage/persistence_exe
  #
  def write_exe_to_target(rexe, rexename, rexepath)
    # check if we have write permission
    if rexepath
      begin
        temprexe = rexepath + "\\" + rexename
        write_file_to_target(temprexe,rexe)
      rescue Rex::Post::Meterpreter::RequestError
        print_warning("Insufficient privileges to write in #{rexepath}, writing to %TEMP%")
        temprexe = session.sys.config.getenv('TEMP') + "\\" + rexename
        write_file_to_target(temprexe,rexe)
      end

    # Write to %temp% directory if not set REMOTE_EXE_PATH
    else
      temprexe = session.sys.config.getenv('TEMP') + "\\" + rexename
      write_file_to_target(temprexe,rexe)
    end

    print_good("Meterpreter service exe written to #{temprexe}")

    @clean_up_rc << "execute -H -i -f taskkill.exe -a \"/f /im #{rexename}\"\n" # Use interact to wait until the task ended.
    @clean_up_rc << "rm \"#{temprexe.gsub("\\", "\\\\\\\\")}\"\n"

    temprexe
  end

  def write_file_to_target(temprexe,rexe)
    fd = session.fs.file.new(temprexe, "wb")
    fd.write(rexe)
    fd.close
  end

A whole bunch of method calls, such as session.fs.file, are meterpreter only.
