sha1_file: convert index_path and index_fd to struct object_id

Convert these two functions and the functions that underlie them to take
pointers to struct object_id.  This is a prerequisite to convert
resolve_gitlink_ref.  Fix a stray tab in the middle of the index_mem
call in index_pipe by converting it to a space.
