Nicola Murino 1c17e20020 ssh: fix certificate authentication with OpenSSH 7.2-7.7 ...

OpenSSH 7.2-7.7 advertises support for rsa-sha2-256 and rsa-sha2-512
in the "server-sig-algs" extension but doesn't support these
algorithms for certificate authentication, so if the server rejects
the key try to use the obtained algorithm as if "server-sig-algs" had
not been implemented.

Fixes golang/go#58371
