Subject: [PATCH] rcpu: avoid filedescriptor conflict with <{} (thanks
 mycroftiv)

the rcpu client dup's fd 0,1,2 to fd 10,11,12 which
can accidentally override the pipe file descriptor
allocated by the <{} operator. to avoid this problem,
we generate the remote script as an /env file in a
separate step now.
