Upstream SSH has been claiming [1] for a few releases now that:
```
It is now possible to perform chosen-prefix attacks against the
SHA-1 algorithm for less than USD$50K. For this reason, we will be
disabling the "ssh-rsa" public key signature algorithm by default in a
near-future release.
```
In Fedora we switched recently [2] to disallow ssh-rsa. I filed a bug
upstream [3] for Vagrant to stop using an rsa key. For now let's workaround
the issue.

With moving to grub2 we now need to remove the extlinux bits from the
other cloud images. They were missed in the move

It gets installed at box launch time anyway. Save users the
annoyance of having to wait. This is in line with the Atomic
Vagrant images as well, which contain rsync in the composed tree.
