[Buildroot] [PATCH 1/2] package/jsoncpp: switch build system to meson

[Bernd Kuhls]

Bumping jsoncpp to 1.9.1 will cause a CMake-related build error:
https://github.com/open-source-parsers/jsoncpp/issues/970

To fix the bug upstream suggests to switch to meson:
"Our official policy has been only supporting the meson build, and
 having users submit fixes for the CMake build."
https://github.com/open-source-parsers/jsoncpp/issues/970#issuecomment-509794015

Remove all _CONF_OPTS as they are not supported by meson.
