[PATCH v2 5/5] test-lib-functions.sh: remove unused [de]packetize() functions

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

Remove the now-unused "packetize()" and "depacketize()" functions
added in 4414a150025 (t/lib-git-daemon: add network-protocol helpers,
2018-01-24). As discussed in the preceding commits we've now moved all
their users over to "test-tool pkt-line".
