Add cannon-prestate as prereq to devnet-up

The devnet-up ultimately requires the cannont-prestate target to have
already executed, or the script errors out.  Consequently, for someone
checking out the repo if they simply do a:

```
make && make devnet-up
```

Things still fail.  This change simply mirrors a similar check added to
the e2e Makefile.

Ensures that pre-image files are always completely written before being moved into place.

cannon: Prevent deadlock on pre-image reads

Reading a FileChannel that does not have a writer blocks
indefinitely. This occurs in cannon whenever the pre-image oracle
server shuts down prematurely. We add a new io.ReadWriter that can
detect when a FileChannel would otherwise block indefinitely.
