    Make mach_msg_header_t have the same size for both 64 bit kernel and 
userland.
    
    This has several advantages:
    1) We don't need to resize mach_msg_header_t, it is just a copy.
    2) Mig won't require any changes because it statically computes the size
       of mach_msg_header_t, otherwise we would need two sizes (28 vs 32 bytes).
