New securityonion-bro-scripts package fixes a race condition

A new version of our securityonion-bro-scripts package is now available that fixes a possible race condition.

This update resolves the following issue:
Issue 374: Update hostname.bro and interface.bro

Thanks to Jon Siwek for the new Bro scripts!
Thanks to the following for testing the new packages!

The new packages are now available in our stable repo.  Please see our Upgrade page for full upgrade instructions:

After installing the new packages, you'll need to restart Bro:
sudo broctl restart

Under certain conditions, the old Bro scripts would fail to determine the hostname and interface...

...resulting in Bro's conn.log containing an invalid "sensorname" field (should be hostname-interface)

Installing new securityonion-bro-scripts package

Restarting Bro

Bro now properly determines hostname and interface resulting in...
...conn.log having the correct sensorname (hostname-interface)
