Description
===========
      
When using replication, the slave will not log any slow query
logs queries replicated from the master, even if the
option "--log-slow-slave-statements" is set and these take more
than "log_query_time" to execute.
                    
In order to log slow queries in replicated thread one needs to
set the --log-slow-slave-statements, so that the SQL thread is
initialized with the correct switch. Although setting this flag
correctly configures the slave thread option to log slow queries,
there is an issue with the condition that is used to check
whether to log the slow query or not. When replaying binlog
events the statement contains the SET TIMESTAMP clause which will
force the slow logging condition check to fail. Consequently, the
slow query logging will not take place.
                    
This patch addresses this issue by removing the second condition
from the log_slow_statements as it prevents slow queries to be
binlogged and seems to be deprecated.
