samples: sensor: Add a delay to the fxos8700 sample loop

The fxos8700 sample application configures the sensor driver to sample
data at 6.25 Hz. Most configurations use the sensor data ready interrupt
to throttle the loop, but it's possible to configure the sample not to
use the data ready interrupt. In this case, throttle the loop with a
delay so it doesn't outpace the sensor data.
