Description: Open the PAM session in the parent process.
This is necessary when logind is running. pam_systemd communicates with logind
and sets up a file descriptor that represents the session. When this file
descriptor is closed, logind will close the session and kill all processes as
part of that. The file descriptor is marked CLOEXEC, so without this patch,
the file descriptor gets opened, then wdm exec()s the session and the file
descriptor is closed, leading to logind immediately killing the session.
This patch makes wdm do PAM session handling the same way that xdm does it.
