fix const-correctness of write_sha1_file
These should take const buffers as input data, but zlib's next_in pointer is not const-correct. Let's fix it at the zlib level, though, so the cast happens in one obvious place. This should be safe, as a similar cast is used in zlib's example code for a const array. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
