tests: Speed up tests by only using parts of the image

Browse Source 
We just need large enough samples to tell them apart correctly. For this
a 128x128 area from the center of each image is sufficient.

This speeds up the test run considerably. Other ways of achieving this
could be to also lower the number of enroll steps for the image device.
