login: T4943: use pam-auth-update to enable/disable Google authenticator
The initial version always enabled Google authenticator (2FA/MFA) support by
hardcoding the PAM module for sshd and login.
This change only enables the PAM module on demand if any use has 2FA/MFA
configured. Enabling the module is done system wide via pam-auth-update by
using a predefined template.
Can be tested using:
set system login user vyos authentication plaintext-password vyos
set system login user vyos authentication otp key 'QY735IG5HDHBFHS5W7Y2A4EM274SMT3O'
See https://docs.vyos.io/en/latest/configuration/system/login.html for additional
details.
(cherry picked from commit e134dc4171b051d0f98c7151ef32a347bc4f87e2)
