Fix OSS build

[markbhasawut]

D89334763 introduced the use of include "thrift/annotation/thrift.thrift" in carbon_result.thrift.

Making all in carbon

This should be fixed by -I $(INSTALL_DIR)/include/ for generating gen-cpp2 for carbon_result.thrift.

D89393569 exposed the component of Tupperware which is a Meta-only tool, so guarding the section related to TW with MCROUTER_OSS_BUILD to fix the issue for OSS build.
