You can write your own file collector that will just delete the file on 
rotation. You will have to implement the `collector` interface:

https://github.com/boostorg/log/blob/ca227bc2f30d65f14719a674247728647caa2b2f/include/boost/log/sinks/text_file_backend.hpp#L74

Then you can set your collector to the sink backend and use the 
rotation_size named parameter to limit the file size.
