Subject: [PATCH] build: Add new dependency on json-c

This will eventually replace Jansson for all JSON parsing.  However
this commit simply introduces the new dependency in the configure
script and documents it.

I chose json-c 0.14 as the baseline since that is the version in RHEL 9.
Probably earlier versions would work.
