sshd.service, ssh@.service, systemd-update-utmp-runlevel.service, and
systemd-update-utmp-shutdown.service have auditd.service in their
After= field; several others have plymouth services. After= is just
for ordering of units, is not a requirement; systemd detects that
auditd.service doesn't exists, and it starts the units that have it in
ther After= field anyway. To make a unit depend on another, you need
Require=.

You can mask the services you don't have by creating a soft link to /dev/null:

# ll /etc/systemd/system/rc-local.service
lrwxrwxrwx 1 root root 9 Aug 16 13:51
/etc/systemd/system/rc-local.service -> /dev/null

It cleans up the output of systemctl --full --all.

Well, I have no idea why your gdm is not letting you log in; obviously
it's related to polkit (since it started when you changed from
consolekit to polkit), but nothing in your config seems to differ from
mine. It is not impossible that somehow the configuration files of the
gdm user got messed up when the change happened. I don't know how this
could happen, but as a hail Mary you could delete /var/lib/gdm, and
reemerge it so it gets a clean install.

Also, you have USE=pam for polkit, right? And could you post the
output from "journalctl -b /usr/lib/polkit-1/polkitd"?
