[PATCH 6/6] json-writer.[ch]: remove unused formatting functions

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

These were added in 75459410edd (json_writer: new routines to create
JSON data, 2018-07-13) for future use with trace2, but have not been
used by anything. These are easy enough to bring back should we need
them, but until then there's no point in carrying them.
