[settings] Fingerprint wakeups are disabled by default. JB#42135

How well fingerprint wakeups work while device is allowed to suspend and
how much battery drain is induced from keeping the scanner active varies
from one device to another.

Make it so that fingerprint wakeups are disabled by default.

Device specific configuration files can be used to override this built-in
default when appropriate, and users can always opt in via execting from
command line:

- mcetool --set-fingerprint-wakeup-mode=proximity
    Fingerprint scanner is activated and used for waking up device when
    the scanner is not used for authentication purposes and proximity
    sensor is not covered.

- mcetool --set-fingerprint-wakeup-mode=always
    Fingerprint scanner is activated and used for waking up device when
    the scanner is not used for authentication purposes.

- mcetool --set-fingerprint-wakeup-mode=never
    Fingerprint scanner is not used for waking up device.
