embObjMultipleFTsensors: Set the status to MAS_OK even if the timeout check is disabled

[traversaro]

#871 introduce one critical bug in the embObjMultipleFTsensors YARP device: as for some reason the default value of checkUpdateTimeoutFlag_ is false, no check if the sensor is in timeout is done. As the assigned of the status to MAS_OK only happens if the check for timeout is done, what happened since #871 is that the sensor always returned the initial status MAS_WAITING_FOR_FIRST_READ, even if a first read already arrived.

This resulted in yarprobotinterface logs flooded by messages like:

and no FT measure was published on the YARP port.

This PR fixes the bug by setting the MAS_OK status whenever a new data is read, so that the status is correctly set even if no timeout is ever checked.

There could be more have been left out as it is more important to provide a bugfix as soon as possible:

• Enable timeout check, by setting checkUpdateTimeoutFlag_ to true
• Provide a different status for temperature readings and for FT readings, as given that the period of the two sensors is different, it is possible that while an FT sensor reading is available, for the temperature the first read has not been done.

@pattacini @Nicogene: unfortunatly this bug is quite critical, as it prevents users of iCub that use embObjMultipleFTsensors from reading the FT sensors on the robot.
