[PATCH 1/2] pkt-line.[ch]: remove unused packet_buf_write_len()

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

This function was added in f1f4d8acf40 (pkt-line: add
packet_buf_write_len function, 2018-03-15) for use in
0f1dc53f45d (remote-curl: implement stateless-connect command,
2018-03-15).

In a97d00799a1 (remote-curl: use post_rpc() for protocol v2 also,
2019-02-21) that only user of it went away, let's remove it.
