[PATCH 1/2] pkt-line: fix declaration of `set_packet_header()`

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

When this function was changed in a97d00799a19 (remote-curl: use
post_rpc() for protocol v2 also, 2019-02-21) from file-local to global,
the declaration was incorrectly missing the `const` qualifier.

Let's fix that.
