pack-write: use hashwrite_be32() instead of double-buffering array

hashwrite() already buffers writes, so pass the fanout table entries individually via hashwrite_be32(), which also does the endianess conversion for us. This avoids a memory copy, shortens the code and reduces the number of magic numbers. Signed-off-by: René Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
