(maint) Do not build with openssl

Unfortunately, openssl 1.0.1g is not available on all debian platforms
for user. The most recent version Debian 7 provides is 1.0.1e. Lucid has
0.9.8k. Since defining dynamic dependncies is more complicated for
debian, this is our solution. We will be building our own openssl that
will be available everywhere to build against, so this is a temporary
removal.
