Apply fix for "pathological case of huffman coding" from toybox's bunzip.c.

Quoting the original commit message:

> A pathological case of huffman coding that uses 8 bits to code each
> of 256 symbols could cause an unsigned char limit[8] to wrap back to
> 0, setting limit to -1 and making the decompressor exit with a data
> error.
