Fix VS2013 build of QUIC radix tests

Visual Studio 2013 does not provide the C99 __func__ predefined identifier in C mode. Use OPENSSL_FUNC, which maps to the compiler-supported equivalent.

This is the only source change required to compile current master with VS2013 Update 5 (cl 18.00.40629), on both x86 and x64.
