WL#3368 mixed binlog_format default

  
  An amendment for parsing argument in case NDB is compiled and active.
  NDB switches from mixed to row-based and back per each query. The previous patch
  was not aware of such behaviour and made exceptional assingment to row-based when
  no command line arg --binlog-format provided.
  
  Removing #if HAVE_NDB_BINLOG block alltogether: ndb supports mixed and if server 
  was build without NDB using binlog nothing to care.
  Test for this piece of code is rather specific. While there is active bug23110
  ndb_alter_table and some other should fail if no explict --binlog-format is given:
