security-misc /usr/share/pam-configs/permission-lockdown-security-misc is no longer required, removed. 
Thereby fix apparmor issue.

> Dec 08 09:47:50 host audit[3232]: AVC apparmor="DENIED" operation="exec" profile="/usr/bin/whonixcheck" name="/usr/lib/security-misc/permission-lockdown" pid=3232 comm="sudo" requested_mask="x" denied_mask="x" fsuid=0 ouid=0
> Dec 08 09:47:50 host sudo[3232]: pam_exec(sudo:session): execve(/usr/lib/security-misc/permission-lockdown,...) failed: Permission denied

It is no longer required, because...

existing linux user accounts:

* Get permission lock down because security-misc `debian/security-misc.postinst` calls `/usr/lib/security-misc/permission-lockdown`.

new linux user accounts (created at first boot):

* security-misc `/usr/share/pam-configs/mkhomedir-security-misc` pam mkhomedir sets secure permissions using `umask=027`.

add console lockdown to pam info output 2019-12-07 06:25:45 -05:00
Patrick Schleizer
6479c883bf
Console Lockdown. 
Allow members of group 'console' to use tty1 to tty7. Everyone else except
members of group 'console-unrestricted' are restricted from using console
using ancient, unpopular login methods such as using /bin/login over networks,
which might be exploitable. (CVE-2001-0797)

Not enabled by default in this package since this package does not know which
users shall be added to group 'console'.

In new Whonix builds, user 'user" will be added to group 'console' and
pam console-lockdown enabled by package anon-base-files.

pam_tally2-info: fix, do nothing when started as user "user" 
xscreensaver runs as user "user", therefore pam_tally2 cannot function.
xscreensaver has its own failed login counter.

as user "user"
/sbin/pam_tally2 -u user
pam_tally2: Error opening /var/log/tallylog for update: Permission denied
/sbin/pam_tally2: Authentication error

effectively (not directly) add "required pam_tally2.so debug" to /etc/pam.d/common-account 
This is required because otherwise something like "sudo bash" would count as a
failed login for pam_tally2 even though it was successful.
