cef2814a4f nixos: add optional process information hiding
This module adds an option `security.hideProcessInformation` that, when
enabled, restricts access to process information such as command-line
arguments to the process owner.  The module adds a static group "proc"
whose members are exempt from process information hiding.

Ideally, this feature would be implemented by simply adding the
appropriate mount options to `fileSystems."/proc".fsOptions`, but this
was found to not work in vmtests. To ensure that process information
hiding is enforced, we use a systemd service unit that remounts `/proc`
after `systemd-remount-fs.service` has completed.

To verify the correctness of the feature, simple tests were added to
nixos/tests/misc: the test ensures that unprivileged users cannot see
process information owned by another user, while members of "proc" CAN.

Thanks to @abbradar for feedback and suggestions.

These are:
 - enable - enable the OATH pam module

63bfe20b72 security.audit: add NixOS module
Part of the way towards #11864. We still don't have the auditd
userland logging daemon, but journald also tracks audit logs so we
can already use this.

a05a340e26 PAM: reorganize the way pam_ecryptfs and pam_mount get their password
Run pam_unix an additional time rather than switching it from sufficient
to required. This fixes a potential security issue for
ecryptfs/pam_mount users as with pam_deny gone, if cfg.unixAuth = False
then it is possible to login without a password.

- fix passphrase rewrapper (password changing should now work fine) as
  discussed on https://bugs.launchpad.net/ecryptfs/+bug/1486470
- add lsof dependency so ecryptfs-migrate-home should work out of the
  box

2e0933787b nixos: add AppArmor PAM support
Enables attaching AppArmor profiles at the user/group level.

This is not intended to be used directly, but as part of a
role-based access control scheme. For now, profile attachment
is 'session optional', but should be changed to 'required' once
a more comprehensive solution is in place.
