package/mesa3d: enable llvm RTTI when needed

LLVM must be built with rtti (runtime type information) support
to build the Gallium Nouveau driver or the Clover OpenCL state
tracker when llvm support is enabled in mesa3d.

Fixes the build when BR2_PACKAGE_MESA3D_OPENCL is set:
"The Clover OpenCL state tracker requires rtti, you need to turn off clover or use an LLVM built with LLVM_ENABLE_RTTI."

This check was added by mesa3d 19.1:

Fixes the build when BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_NOUVEAU and BR2_PACKAGE_MESA3D_LLVM are set
"The Nouveau driver requires rtti. You either need to turn off nouveau or use an LLVM built with LLVM_ENABLE_RTTI."

This check was added by mesa3d 19.0:
