    Add wrapper function for write.
    
    gcc-4.5.4 on NetBSD complains:
    xdm/prngc.c: In function ‘get_prngd_bytes’:
    xdm/prngc.c:133:2: error: passing argument 1 of ‘atomicio’ from incompatible pointer type
    xdm/prngc.c:46:16: note: expected ‘ssize_t (*)(int,  void *, size_t)’ but argument is of type ‘ssize_t (*)(int,  const void *, size_t)’
    
    The problem is that the read(2) and write(2) syscalls differ
    in the const-ness of their second argument. The wrapper
    function gets rid of the difference.
