drm-tests: update to _FORTIFY_SOURCE=3

Since this project explicitly specifies its FORTIFY level, update it to
the level CrOS wants to move to. This isn't _removed_, since it's copied
from a template file, and consistency with that seems useful.

The template file this was copied from was updated in
crrev.com/c/4735413.
