applehv: Remove unneeded cmd.ExtraFiles assignment

`applehv.Start()` has this line of code:
```
cmd.ExtraFiles = []*os.File{ioEater, ioEater, ioEater}
```
whose purpose is not clear.

The intent may have been to redirect stdin/stdout/stderr to /dev/null in
the child process.
This should be done by setting cmd.Stdin/cmd.Stdout/cmd/Stderr to nil,
which is the case by default.

The way it's done could also cause issues as
`Vfkit.VirtualMachine.Cmd()` sometimes adds files it needs to keep open
to `ExtraFiles`, so at the very least this should be an `append()`

This commit removes this code.

[NO NEW TESTS NEEDED]
