renderer/native: Don't use modifiers to import linear DMA buffer

Browse Source 
When the buffer modifier is DRM_FORMAT_MOD_LINEAR, we can use the
old code path. That means not specifying any modifier parameter.

It was an issue when the primary GPU was creating a linear GBM surface
and that a secondary GPU (not supporting modifiers) was trying to
import it. It was failing because the driver could not use the
import_modifiers extension even though it could in theory easily
import the buffer.
