Remove suid / gid and execute permission for 'group' and 'others'. 
Similar to: chmod og-ugx /path/to/filename

Removing execution permission is useful to make binaries such as 'su' fail closed rather
than fail open if suid was removed from these.

Do not remove read access since no security benefit and easier to manually undo for users.

chmod 744

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 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

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.
