Remove libssh

libssh is LGPL licensed, which means I would need to re-license the
entire app since we are linking against it statically. I could
dynamically link against it, but since I was only trying to use it for
key-generation and that doesn' seem to be working, I may as well discard
it.

For now, I'm going to stick with jsch for the key generation. On ios
side, I'm not sure what I will do. One option could be to compile
openssh and call the ssh-keygen binary.
