[Bug 1098299] [NEW] entropy pool should be seeded earlier in boot process

[Marc Deslauriers]

*** This bug is a security vulnerability ***

Public security bug reported:

Currently, the entropy pool is seeded by /etc/init.d/urandom. This
should be done earlier in the boot process by an upstart job, and should
be done before the ssh daemon is started.

Although the ssh keys are generated on package install, openssh uses
openssl's PRNG which is seeded on boot for ephemeral keys.

See https://factorable.net/weakkeys12.extended.pdf for more information.
