compat/mingw.c: remove printf format warning

5096d490 (convert trivial sprintf / strcpy calls to xsnprintf) converted
two sprintf calls. Now GCC warns that "format '%u' expects argument of
type 'unsigned int', but argument 4 has type 'long unsigned int'".
Instead of changing the format string, use a variable of type unsigned
in place of the typedef-ed type DWORD, which hides that it is actually an
unsigned long.

There is no correctness issue with the old code because unsigned long and
unsigned are always of the same size on Windows, even in 64-bit builds.
