finger print setup

[Gianluca Cecchi]

also set up authentication with System -> Administration ->
Authentication, checking "Enable Fingerprint reader Support" (strange
that with this disabled I got the button in gnome-about-me before
updating fprintd... )

Then reboot the pc (without kexec but normally).
The situation doesn't change; no button in gnome-about-me
running it directly from command line with strace I can see these
lines if I grep "finger" or "fprint" words, but I don't know if they
are relevant for debugging. Eventually I can attach full strace log
