libpkgconf: define SIZE_FMT_SPECIFIER on POSIX and Windows platforms and use it in place of %zu

The MSVCRT runtime as used on Windows does not support %zu, but instead recommends %Iu.  As we want
to remain portable to other runtimes, even on Windows, we do not use %Iu, but instead expand it logically
to either %lu or %llu depending on if it's _WIN32 or _WIN64 headers.

On POSIX, we assume C99 support is available and always use %zu, as pkgconf has never supported anything
earlier than C99 officially.

Closes #125.
