Extend the existing test case to cover:
1. Invalid flag atribute in the struct drm_mode_fb_cmd2.
2. Pixel format which requires non-linear modifier with
DRM_FORMAT_MOD_LINEAR set.
3. Buffer offset for inexistent plane

v2:
- Remove strcpy to strscpy change.
v3:
- Rename and commment the "Buffer offset for inexistent plane"
test case.
