Bug #18607: LOAD DATA FROM MASTER fails because of INFORMATION_SCHEMA database

  Simply exclude INFORMATION_SCHEMA from LOAD DATA FROM MASTER just like
  we exclude the `mysql` database.

  There's no test for this, because it requires an unfiltered 'LOAD DATA
  FROM MASTER' which is too likely to cause chaos (such as when running
  the test suite against an external server).
