Move setting of 'fp2.cam.any.changed' property outside loop

Camera resolution preferences are wiped if a different camera module is
detected compared to previous boot. init.fp.camera_preference_wipe.sh
reads 'fp2.cam.(main|front).changed' properties and removes resolution
settings for the ones that are changed.

A race occurs because the service to remove resolution settings is
started when 'fp2.cam.any.changed' is set to 1 inside the loop that also
sets 'fp2.cam.(main|front).changed' sequentially. The service may have
been started and run before 'fp2.cam.front.changed' is set if both
sensors have changed.

This change moves setting 'fp2.cam.any.changes' outside of the loop to
prevent this race.
