[PATCH] remove SSL support

[Eric Wong <e@80x24.org>]

We implemented barely-advertised support for SSL for two reasons:

1) to detect corruption on LANs beyond what TCP offers
2) to support other servers based on unicorn (never happened)

Since this feature is largely not useful for unicorn itself,
there's no reason to penalize unicorn 5.x users with bloat.

In our defense, SSL support appeared in version 4.2.0 :)
