authPrompt: support smartcard authentication

This commit detects when a user inserts a smartcard,
and then initiates user verification using the gdm-smartcard
PAM service.

Likewise, if a user removes their smartcard, password verification
(or the user list depending on auth mode and configuration) are initiated
