modesetting: Fix msSharePixmapBacking returning a non-linear bo

Browse Source 
glamor_fd_from_pixmap() may return a tiled bo, which is not suitable
for sharing with another GPU as tiling usually is GPU specific.

Switch to glamor_shareable_fd_from_pixmap(), which always returns a
linear bo. This fixes mis-rendering when running the mode setting
driver on the master gpu in a dual-gpu setup and running an opengl
app with DRI_PRIME=1.
