examples: Remove sleep call in enroll examples

Browse source 
The call to sleep(1) inside of the enrollment loop caused a crash
on at least the etes603 driver.

Because in fp_enroll_finger_img the function enters an event
handling loop. This loop needs to start before the next libusb
event timeout. Which would not happen in the etes603 driver
because the timeout there was set to 1 second as well.
