Some DRM tests cross the 1s execution time threshold that defines a test
as slow. Let's flag them as such.

Curious that both did not trigger for me and I even run them under 
nested qemu most of the time.

This one deliberately aims to run for ~1s and I don't have an immediate 
idea how it would go over 2s.
