Subject: [PATCH] pam: Do not use tally2 if faillock is present
From pam 1.4.0 release notes:
Deprecated pam_tally and pam_tally2: these modules are no longer built
by default and will be removed in the next release, use pam_faillock
instead.
https://github.com/linux-pam/linux-pam/releases/tag/v1.4.0
Fixes #1313
