Test cpp_dummy_build in pedantic mode

Browse Source 
In public headers, we want to avoid things that are not standard C++,
including features that GCC and Clang support as extensions, such as
flexible array members. So compile with `-pedantic`.

Non-regression for https://github.com/Mbed-TLS/mbedtls/issues/9020.
