Redmine#5667 - address ps -axo shift on FreeBSD 10.0-RELEASE and later

As discussed and documented in Redmine#5667 , there's an inevitable creep to the right going on in FreeBSD 10 and later which has been demonstrated to break bootstrapping in a severe fashion. Going with the most elegant fix, which is to just say 'auxw' in line with Darwin, which is closest for these purposes. Output and column starts do not change, just guarantees getting complete lines regardless of terminal width. Quick test shows no impact.
Note that columns with -axo DO variably shift now on 10 and later, so systems with long runtimes trying to bootstrap are likely to encounter the described bug.

Disable all renegotiation, resumption options and set safest defaults.

Reason is we want to expose a minimal attack surface on the very complex
TLS protocol and its implementations.

To disable TLS renegotiation and session resumption we need to turn off
the server-side session cache *and* disable session tickets (RFC 5077)
extension, see [1]. In the future we can always selectively re-enable
options in order to gain a performance boost.

Since we do not care about cross-browser compatibility and web, we also
disable all OpenSSL defaults that help with backwards compatibility.
