When the servername driver-opt is set it is also used for TLS SNI and
certificate validation, so use it for the gRPC ":authority" pseudo-header
as well, falling back to the endpoint host otherwise. This matches how the
buildkit client derives the authority from the server name when TLS
credentials are supplied.
Since the driver terminates TLS in its own dialer, the authority is set
explicitly via client.WithGRPCDialOption(grpc.WithAuthority(...)).
