Revert "Add tokens for EGL_EXT_image_dma_buf_import_modifiers"

This reverts commit 1c20cd090b0f32605bb7d4b5bccbca4f32e5eb86.

This was chumped w/out explanation, and the bots have all been
dead since due to graphics_Gbm check failures.  Reverting in
the hope it'll fix things.  It can reland via the CQ.
