tetragon: Move base sensor initialization to GetInitialSensor

Currently we initialize the base sensor when the sensor when the application is started even for command like --help which does not really needs it. Moving the progs/maps sensor init to GetInitialSensor so it's initialized when the sensor is actually needed. Signed-off-by: Jiri Olsa <[email protected]>
