pam_motd: Export MOTD_SHOWN=pam after showing MOTD
This is a useful indication for update-motd profile.d snippet which can
also try to show MOTD when it is not already shown.
The use-case for that is showing MOTD in shells in containers without
PAM being involved.
* modules/pam_motd/pam_motd.c: Export MOTD_SHOWN=pam after showing MOTD
* modules/pam_motd/pam_motd.8.xml: Mention setting MOTD_SHOWN=pam in the man page
