[PATCH] fetch-pack: Add missing line-feed character when sending depth-request packet line

[Stan Hu <stanhu@gmail.com>]

The pkt-line format mandates: "a sender should include a LF, but the
receive MUST NOT complain if it is not present." This patch
is not absolutely necessary since receivers handle the missing the LF,
but this patch adds it for good measure.
