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

[Topi Pohjolainen]

v2 (Chad): add dependency to 'EGL_KHR_image_base'

v3: cast 'GLuint' into 'intptr_t' before trying to cast to
    'EGLClientBuffer'. Makes compiler happy on platforms where
    integer and pointer are of different size.
