Fix printf-related compilation warnings on MinGW

* src/conf_post.h (ATTRIBUTE_FORMAT_PRINTF) [__MINGW32__]: Use
'__ms_printf__', not '__gnu_printf__', as the latter is not what
MS 'printf' supports, and causes bogus compilation warnings.
* src/lisp.h (pI) [__MINGW32__]: Define to "I64", as MS 'printf'
doesn't support the "ll" modifier.
