wayland/dma-buf: Enable modifiers by default on non-native backend

Browse Source 
If the used EGL backend supports it. In practice this should currently
only affect the nested backend.

Enabling modifiers can help with app development. An example is
`weston-simple-dmabuf-v4l`, which requires the linear modifier to be
available.

Note that Weston behaves similar already.
