re-enable SSH support
This was disabled by default upstream with the 1.4 release, but is required for cargo (via rust-git2 / rust-libgit2-sys).
I am currently working on updating cargo (which in recent upstream versions transitively depends on libgit2 1.4), so I'd appreciate a re-upload to experimental with SSH enabled! Thanks :)
