include: change RegionSize() to take a size_t

/usr/include/xorg/regionstr.h:130:36: warning: implicit conversion changes
signedness: 'int' to 'unsigned long' [-Wsign-conversion]
    return (sizeof(RegDataRec) + ((n) * sizeof(BoxRec)));
                                   ^  ~

Really only just pushes the problem to the caller, but maybe that motivates
someone to fix it.
