We use the keyring, so let's make sure it gets properly initialized for
sessions in factory reset mode.

Apparently PAM reacts differently on different systems (?) and if no
authoritative matching module is found might either succeed/fail,
depending on the system.
Let's lock this down explicitly, by hooking in pam_deny.so.
Of course, these PAM files are just examples, and no distro in its right
mind would ship these unmodified, but let's default to something safe.
Fixes: #12950

This commit replays the moving around of source files that have been
done between systemd-219 and systemd-221.
Further the Makefile.am is synchronized with the upstream version and
then "re-cleaned".
A lot of functions, that are not used anywhere in elogind have been
coated into #if 0/#endif directives to further shorten the list of
dependencies.
All unneeded files have been removed.
Stupid PAM, please just go away!
