pam-selinux 1.4.0-3 update

[fishilico]

Hi,
Here is an upgrade for package pam-selinux, that I am testing. As a maintainer, I do not want to push the upgrade pam-selinux to version 1.4.0 before the official pam package gets upgraded, as it caused multiple issues during Arch Linux's testing (cf. https://bugs.archlinux.org/task/67347, https://bugs.archlinux.org/task/67519 and https://bugs.archlinux.org/task/67369, as well as the 3 patches that have been backported).

I also added --enable-tally2 to work around issue #41. By the way, I mainly open this PR in order to enable users to "just cherry-pick a commit or checkout a git branch" in order to build packages, considering the incompatibility between libselinux 3.1 and pam 1.3 (cf. #37).

Feel free to test this package and report issues and suggest improvements in this Pull Request.

Figured, I'd let you know that this branch works, with the bulk update. And as expected I was able to log in without migrating off pam tally.

Thanks for this.
Also tested build on this branch, and it works with no imminent issues.

It looks like 1.4.0-3 made it to core repositories, so I think this branch is good to go.

EDIT: pambase needs an update naturally

Before upgrading, I wanted to solve a potential issue for users upgrading that install pambase-selinux 20200721.1-2 before pam-selinux 1.4.0-3, which breaks the system (and makes sudo and su no longer works).

By adding --enable-tally2 in pam-selinux like I did in this Pull Request, pam-selinux can safely be upgraded before pambase-selinux. So a possible way to fix this consists in making pambase-selinux depends on pam-selinux>=1.4.0 (in order to have module pam_faillock.so). This is the contrary of the current dependency link (pam depends on pambase).

In fact, this inversion of dependency link makes sense in itself, because pambase-selinux provides configuration files with pam_selinux.so, which is only provided in pam-selinux package. So it makes completely sense to ensure that pam-selinux is installed before pambase-selinux.

I added commits to this Pull Request to do this. If nobody find issues with this approach, I will update the packages in a few days.

I built & installed with this branch along with the recent pull requests I made.
#48
#50
#51

No errors to report. Also updating a running bare-metal system did fine.
