[Buildroot] [git commit] package/rapidjson: switch to CMake

commit: https://git.buildroot.net/buildroot/commit/?id=e810284ccb055dcab6dcf6abf41a15a77ee7888a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Upcoming Kodi v18 depends on RapidJSON and detects it by using pkg-conf:
https://github.com/xbmc/xbmc/blob/master/cmake/modules/FindRapidJSON.cmake#L13

Currently our package installs only the header files, but RapidJSON.pc
is also needed. Luckily this can be fixed by switching to CMake which
does the job, also add configure options to disable the CMake build of
executables.
