JD Friedrikson a0052fdb68 Specify InsecureIgnoreHostKey for HostKeyCallback ...

[A recent breaking change upstream in Golang's crypto
library](https://github.com/golang/crypto/commit/e4e2799dd7aab89f583e1d898300d96367750991)
has broken SSH connectivity for a few builders:

```

```

Specifying HostKeyCallback as insecure should make things work again
and would make sense for packer's use case.
