[Piglit] [v10 12/13] tests/spec: EXT_image_dma_buf_import intel dma-buf with img-ext only

v2 (Chad):
   - be more specific: rename try_as_non_external_texture() as
     try_as_texture_2d()
   - skip the test if EGL stack does not support the chosen format
   - add dependency to 'EGL_KHR_image_base'
