EKF: remove check for faulty flag in fake rng
...
This removes the check for _rng_hgt_faulty in the decision of publishing
a fake range measurement. The reason for this is that some distance sensors
don't populate the quality flag, even if they are saturated. Hence, if we
are on the ground and not moving, it is safe to publish a fake measurement
of the distance sensor and overwrite the actual sensor data.

terrain_estimator: introduce quality metric in rng
...
This commit introduces a quality measure in the range data. It is
used to properly decide whether to initialize the HAGL estimate on
sensor data or MIN_HGT parameter, as well as in the decision of
whether a 'fake' measurement should be published on the ground to
allow for optical flow take-offs.

position/velocity aiding sensor.
Until now, it was alway resetting if the vehicle does not have gps or
