Add pam configuration to allow user sessions to work out of the box
systemd-logind will start user@.service. user@.service unit uses PAM with service name 'systemd-user' to perform account and session managment tasks. Previously, the name was 'systemd-shared', it is now changed to 'systemd-user'. Most PAM installations use one common setup for different callers. Based on a quick poll, distributions fall into two camps: those that have system-auth (Redhat, Fedora, CentOS, Arch, Gentoo, Mageia, Mandriva), and those that have common-auth (Debian, Ubuntu, OpenSUSE). Distributions that have system-auth have just one configuration file that contains auth, password, account, and session blocks, and distributions that have common-auth also have common-session, common-password, and common-account. It is thus impossible to use one configuration file which would work for everybody. systemd-user now refers to system-auth, because it seems that the approach with one file is more popular and also easier, so let's follow that.
