[Merge] ~dbungert/livecd-rootfs:adt-hang-vagrant into livecd-rootfs:ubuntu/master

[Dan Bungert]

Dan Bungert has proposed merging ~dbungert/livecd-rootfs:adt-hang-vagrant into livecd-rootfs:ubuntu/master.

Commit message:
cpc/hooks: fix hang when running adt locally

While attempting to run autopkgtest locally, the test stops at the
following command:
ssh-keygen -t ed25519 -C ubuntu_vagrant_insecure_key -b 4096 -f
/tmp/tmp.VuAfnsBv1G/vagrant_insecure_key

This is found in live-build/ubuntu-cpc/hooks.d/base/vagrant.binary

It appears to be waiting for a passphrase, as running that outside of
adt gives a more helpful "Enter passphrase" prompt.

Explicitly set the passphrase to empty with the `-N` argument.
