fixes #12632 - remove hardcoded SSH compression algorithm

net-ssh behaviour changed in 2.10 from treating a specified algorithm
as a preference (and falling back to one it knew) to treating it as a
whitelist of algorithms. OpenSSH servers need the algorithm
`` rather than plain `zlib`, so negotiation failed.
Instead, specify `true` to use net-ssh's list of supported compression
algorithms.
