  Noble: default pam config for login tries do load non-existent
  pam_lastlog.so

Bug description:
  pam_lastlog.so was dropped by upstream in 1.5.3[1][4]. It's still
  there in the code, but not built by default.

  And indeed, in noble (1.5.3) we don't have it, while mantic (1.5.2)
  does.

  This does not prevent console logins, but generates an error in the logs:
  Apr 23 20:02:09 n1 login[835]: PAM unable to dlopen(pam_lastlog.so): /usr/lib/security/pam_lastlog.so: cannot open shared object file: No such file or directory
  Apr 23 20:02:09 n1 login[835]: PAM adding faulty module: pam_lastlog.so

  Debian's shadow package is also still shipping this config[2].

  If you think we should re-enable pam_lastlog, then this becomes a bug
  in the src:pam package, but keep in mind upstream is keen on removing
  it, and we might be better off switching to an alternative, perhaps
  pam_lastlog2[3].
