Fix 32bit build

:Release Notes:
Fixed building for 32bit platform

:Detailed Notes:
Yet another forcing of type to linking with a correct pbnjson
function.
pbnjson::JValue have templated method declaration that accepts any
type, but specialized implementation exists only for a few of them.
It would be good to change that to templated generic implementation
(even if there will be kinda static_assert) in-place together with
forward declaration for specializations.

:Testing Performed:
Verified build for desktop and for bitbake (qemux86).

:QA Notes:

:Issues Addressed:
[GF-52639] possibility to replace NTP with other time source
