fix: ensure correct ssh public key is used for authentication
- The root cause is described in b4f1988a35
- Move to a fork of `github.com/gliderlabs/ssh` that exposes the
permissions that was chosen by `x/crypto/ssh` after succesfully
authenticating, this is the recommended mitigation by the Golang
security team. The fork exposes this, since `gliderlabs/ssh` instead
relies on context values to do so, which is vulnerable to the same
attack, although partially mitigated by the fix in `x/crypto/ssh` it
would not be good practice and defense deep to rely on it.
- Existing tests covers that the functionality is preserved.
- No tests are added to ensure it fixes the described security, the
exploit relies on non-standard SSH behavior it would be too hard to
craft SSH packets to exploit this.
