Andrew Kaster e594724b01 Kernel: mmap(..., MAP_PRIVATE, fd, offset) is not supported ...

Make mmap return -ENOTSUP in this case to make sure users don't get
confused and think they're using a private mapping when it's actually
shared. It's currenlty not possible to open a file and mmap it
MAP_PRIVATE, and change the perms of the private mapping to ones that
don't match the permissions of the underlying file.
