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=poison-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
fails.

Add a recipe that explicitly searches /usr/include, and use that in
oe-selftest to verify that host include paths are correctly causing
build failures.
