Use #defines to replace POSIX functions with emulated ones on MinGW,

like we do on MSVC. This allows us to #undef them when we really need
to use the original platform function (if available).

Disable emulated fstat() in raidfile (and use the platform one) by undefining
fstat, since it doesn't use the other emulated file handling functions, or
need Unicode support, and it can't take a filehandle returned by open()
(only openfile()).
