[Intel-gfx] [PATCH v2 i-g-t] kms_addfb_basic: Require fb modifiers for unused field tests

[Ander Conselvan de Oliveira]

The drm core doesn't check unused fields of ADDFB2 for pre-FB_MODIFIERS
userspace, so use igt_require_fb_modifiers(). Also, the size of the
ioctl changed with the addition of the modifiers, so it is necessary to
use the LOCAL_ version of it, otherwise some data may get truncated.

v2: Improve commit message. (Thomas)
    Remove one spurious change to use LOCAL_DRM_IOCTL_ADDFB2. (Thomas)
