Fix a broken merge.

scripts/mysql_system_tables.sql:
  Add time_zone to the list of mysql.event columns.
scripts/mysql_system_tables_fix.sql:
  Update after a bad merge: now mysql_system_tables_fix contains
  only alter definitions, no CREATE definitions (single definition
  source approach that was implemented by Magnus).
