add opt paths

[zivagolee]

Add /opt/flydata paths to prepare for installation of flydata-mysql-replication-listener package. This should default to normal if it doesn't find it in /opt/flydata.

The change will make ruby-binlog FlyData specific, which we should avoid. Can you come up with a different way?

[zivagolee]

Not really. It does add a path for /opt/flydata but the original paths are still there. This is only so we can compile our ruby-binlog.

This is due to flydata-mysql-replication-listener package now puts the boost headers and libs in /opt/flydata. Reasoning is that although the boost libs are renamed, the headers aren't renamed and can conflict with original system boost packages and it is best to avoid this.
