egl/main: add support for fourth plane tokens

Browse Source 
The EGL_EXT_dma_buf_import_modifiers extension adds support for a
fourth plane, just like DRM KMS API does.

Bump maximum dma_buf plane count to four.

v2: prevent attribute tokens from being parsed if
    EXT_image_dma_buf_import_modifiers is not suported. (Emil Velikov)
