avutil: Include io.h with a separate condition from MapViewOfFile

Browse Source 
The existence of MapViewOfFile isn't linked to the existence of
io.h.

Not all versions of windows have MapViewOfFile (in particular,
Windows Phone 8 and the "metro" windows 8 API subset don't),
while they still have io.h (and need it for open/read/close).
