Bug#41307: Tests using include/ndb_backup.inc won't work on Windows due to 'grep' call.

Revised patch incorporating cleaner test code brought up during review.
Removed the use of grep and accomplished same actions via SQL / use of the server.

Runs as before on *nix systems and now runs on Windows without Cygwin as well.
