build: Opt out from using mingw-w64's replacement printf(), etc.
The Windows code in dbus is careful to use Windows-specific equivalents
of the Standard C features that are not implemented by msvcrt.dll, so
we don't need to substitute a Standard C printf implementation.
This avoids compiler warnings/errors when gcc expects us to be using
Microsoft printf syntax (`ms_printf` attribute), but newer versions of
mingw-w64 expect us to be using GNU or Standard C printf syntax
(`gnu_printf` attribute) as a result of `__USE_MINGW_ANSI_STDIO` being
enabled by default if not otherwise specified.
