Bug#47638 The rpl_killed_ddl test fails on Windows

When the $diff_statement variable for diff_master_slave.inc was
put in multiple lines, the rear part of the statement would be 
missing when being executed on Windows systems.

Fixed the problem by always putting the value for $diff_statement
in one line.
