Fix a few more Jinja2 filters used as tests
...
I had created these earlier in this branch before rebasing it on top
of the Ansible 2.5.0 readiness branch.

Use Ansible's version_compare instead of doing math on strings

I'm surprised this worked all these years actually. Since Ansible
version 1.6 it has been possible to use the version_compare filter
instead of doing math logic on strings.

roles/common: Remove 128-bit Ciphers and MACs from sshd_config

I had removed them from Debian 8 and Ubuntu 14.04 configs last year
when the NSA's Suite B crypto guidelines dropped 128-bit algorithms
but those changes didn't make it to my new Ubuntu 16.04 config.
It is probably overkill and paranoid, but this server is mine, so I
can make those decisions (and I only connect from modern clients).

roles/common: Add sysctl template for Debian hosts
...
Note: I've only tested this on a Debian container, and you can't
set these sysctls on containers (the host controls them). To make
matters worse, there is no fact to make ansible skip this on hosts
that are running in containers. For now I will just skip it on
hosts that are "virtualization" servers... even though we actually
do have KVM running on Debian on real hardware. *sigh*

roles/common: Specify default apt_mirror for fallback in sources.list template
...
New hosts often fail due to not having an apt_mirror, because there
isn't one defined for their group and their host_vars haven't over-
ridden it.
We want new hosts to deploy successfully, so let's just use a default
apt_mirror if there isn't one defined. Rather have a slow mirror than
a failed deployment. And in any case, Linode can download from KENET's
mirror at 10MB/sec. ;)
