Subject: [PATCH] BUG#39858 rpl.rpl_rotate (rpl.rpl_rotate_logs) failed on
 pushbuild: result mismatch

The method to purge binary log files produces different results in some platforms.
The reason is that the purge time is calculated based on table modified time and
that can't guarantee to purge master-bin.000002 in all platforms.(eg. windows)

Use a new way that sets the time to purge binlog file 1 second after the last
modified time of master-bin.000002.
That can be sure that the file is always deleted in any platform.
