libobs-opengl: Load EGL via Glad on Wayland platform 

We need to have EGL extensions loaded when dealing with DMA-BUFs.

EGL_EXT_image_dma_buf_import: This extension is required to import
DMA-BUFs with the modifier-less path. It is limited to buffers with 3
planes. [1]

EGL_EXT_image_dma_buf_import_modifiers: This extension is required to
import DMA-BUFs with an explicit modifier. It raises the limit of buffer
planes to 4, which is the maximum planecount for DMA-BUFs. [2]
