[PATCH][RESEND] lib: fwts_log_json: enable json human readable formatting (LP: #1206290)

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

The current json log output is hard to read as a human. Enable the json
pretty printing (if libjson supports it) to make it easier for mortals to
parse by eye.
