vlock: introduce short delays after non-fatal PAM errors

Add a short delay after PAM errors like PAM_AUTH_ERR that are likely
to be non-fatal, so that in case when they are fatal, there would be
a delay between continuous attempts that are doomed to fail.

For example, fatal PAM configuration errors like unreadable
/etc/pam.d/vlock file usually result to immediate PAM_AUTH_ERR,
the same error as returned by more likely authentication error
due to incorrect password.
