1. Replace binlog file suffix to 000003
2. The patch that makes the test case to pass on freebsd. 
The test relies on a shell script that was executed using MTR 
"system" command. However, "system" was deprecated and the test 
case was changed to use exec + /bin/sh instead (see BUG#11747313).
But the shell script actually needs /bin/bash to succeed, 
otherwise it will just hang, thence the timeout.
Since FreeBSDs boxes seem to have /bin/bash installed, we change 
it from /bin/sh to /bin/bash to make the test pass again.
