drm/tests: Zero initialize fourccs_out

Browse Source 
fourccs_out array is not initialized. As the
drm_fb_build_fourcc_list() doesn't necessarily change all the array,
and the test compares all of it, the comparison could fail if the
array is not initialized. Zero initialize the array to fix this.
