Fix compilation with older MinGW versions
The __MINGW_PRINTF_FORMAT constant has been defined back in 2012
https://sourceforge.net/p/mingw-w64/mingw-w64/ci/77bc5d6103b5fb9f59fbddab1583e69549913312/
However older toolchains are still around and some user reported the
following compilation failure:
flash.h:336:1: error: '__MINGW_PRINTF_FORMAT' is an unrecognized format function type [-Werror=format=]
__attribute__((format(__MINGW_PRINTF_FORMAT, 2, 3)));
Fix this by defining the constant when it isn't already; the change does
not affect other compilers because it's guarded by "#ifdef __MINGW32__".
Setting __MINGW_PRINTF_FORMAT to gnu_printf is exactly what newer MinGW
versions do when __USE_MINGW_ANSI_STDIO is defined, which it is in
flashrom Makefile.
