Revert "openssh: Add FIDO2 hardware token support"

This reverts commit 855db864b0.

The reverted commit doesn't make sense since the component
(ssh-sk-helper) that uses libfido2, which is mentioned in
the commit message, isn't packaged.

-		OpenSSH version 8.2 added two new ssh authentication methods,
-		namely `ecdsa_sk` and `ed25519_sk`. These two methods make use
-		of hardware keys that implement the FIDO and FIDO2 protocols.
-		In order to use these two types, libfido2 is required.
