Bug#23240 --init-file statements with NOW() reports '1970-01-01 11:00:00'as the date time

- Starting time of a query sent by file bootstrapping wasn't initialized
  and starting time defaulted to 0. This later used value by the Now-
  item and is translated to 1970-01-01 11:00:00.
- marking the time with thd->set_time() before the call to 
  mysql_parse resolves this issue.
