[Buildroot] [PATCH 1/1] Openjpeg: Fix malloc poison issue, add C++ and threads dependencies

The malloc poison issue has been fixed upstream, this patch will thus only
be temporary.
Some of the autobuild issues related to missing g++ compilers
and missing threading libraries. Thus the dependency should solve that.
