[FASTFAT] Copy an entire field, instead of half-copying it with RtlCopyMemory

Browse source 
Fixes GCC 8 warning:
sdk/include/crt/mingw32/intrin_x86.h:76:12: error: 'memmove' offset [21, 40] from the object at 'DirContext' is out of the bounds of referenced subobject 'Attrib' with type 'unsigned char' at offset 19 [-Werror=array-bounds]
     return memmove(dest, source, num);
