Required extensions to support wsi have been relaxed earlier for sw blit
path. So the renderer extensions enablement is fixed to be passive based
on the renderer side correspondingly.
Test: emulate to drop dma-buf and modifier support from host anv driver,
and confirm wsi via venus works with sw blit fallback and device
creation no longer returns VK_ERROR_FEATURE_NOT_PRESENT.
Fixes: 06f5d1a105 ("venus: expose WSI on renderer without dma-buf support")
