scd: Print the main app name also for not fully supported cards.

* scd/app.c (send_serialno_and_app_status): Add fallback.

The app list was only printed for apps which support the with_keygrip
function. That is not the case for the netkey and otehr cards. The
new fallback prints the actual app name.
