lib/bitmap.c: remove wrong documentation
This promise is violated in a number of places, e.g. already in the second function below this paragraph. Since I don't think anybody relies on this being true, and since actually honouring it would hurt performance and code size in various places, just remove the paragraph.

* carefully filter out these unused bits from impacting their

- * These operations actually hold to a slightly stronger rule:
- * if you don't input any bitmaps to these ops that have some
- * unused bits set, then they won't output any set unused bits
- * in output bitmaps.
- *
* The byte ordering of bitmaps is more natural on little
* endian architectures. See the big-endian headers
