[PATCH v2 3/5] notes: use existing function stream_blob_to_fd

[Maarten Bosmans <mkbosmans@gmail.com>]

From: Maarten Bosmans <mkbosmans@gmail.com>

From: Maarten Bosmans <maarten.bosmans@vortech.nl>

Use functionality from streaming.c and remove the copy_obj_to_fd()
function local to notes.c.

Streaming the blob to stdout instead of copying through an
intermediate buffer might also be more efficient, but at the
size a typical note is, this is unlikely to matter a lot.
