svga: Force an RGBA view creation for an RGBA resource
glXCreatePixmap() may specify a GLX_TEXTURE_FORMAT_RGB_EXT format
for an RGBA resource, causing us to create an RGBX view for an
RGBA resource, a combination vgpu10 does not support.
When this is detected, change the request to create an RGBA view
instead.
