[PATCH] lib: fwts_json.h: define TRUE and FALSE for newer versions of json-c (LP: #1874224)

[Colin King]

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

BugLink: https://bugs.launchpad.net/bugs/1874224

json-c-0.14 does not provide TRUE/FALSE defines anymore, and instead
only uses 1/0 directly. Add in the defines for TRUE/FALSE if they
don't exist already.

Thanks to Björn Esser for the fix from originally from
https://src.fedoraproject.org/rpms/fwts/c/2d53ef23970e but with
the JSON_C_VERSION_NUM removed as we don't need to be overly
pedantic here.
