The original motivation was user convenience, allowing the user to type "sudo broctl" instead of "sudo /opt/bro/bin/broctl". This setting needs to be removed now for a few reasons:

• Ubuntu recently updated the default secure_path setting but that setting was being overridden by our setting. By removing our setting, we allow the standard default to take effect.

• We're adding a new script /usr/sbin/broctl (NSM: create /usr/sbin/broctl #1043) that will run /opt/bro/bin/broctl as a limited user. So now when a user types "sudo broctl" it will do the right thing with the default Ubuntu secure_path setting.
