Patches CMake files in flatcc to conditionally set c++ as a required
language depending on if FLATCC_TEST option is set, as only the tests
include a c++ file.

+Subject: [PATCH] CMakeLists.txt: conditionally require C++ based on
+ FLATCC_TEST (#94)
+C++ is only used when building the tests, so only include it as a
+language via project() when FLATCC_TEST is enabled. This allows
+toolchains that don't have C++ to build flatcc.
