[PATCH 1/3] meta-selftest/poison: improve sysroot poisoning test case

Ross Burton

It was discovered by Martin Jansa that the sysroot poisoning errors are
not functioning as they should. Due to either a bug from day 1 or a
bad rebase, -Werror=3Dpoison-system-directories is only passed when GCC
is invoking _just_ the preprocessor, not the compiler.

Demonstrate this by expanding the test case to exercise not just $CPP,
but also $CC for both C and C++ languages. This improved test case now
