linux: use XShmPutImage when SHM Pixmap APIs unavailable
SHM Pixmaps were frequently unavailable (which makes some
sense: you're asking for a shared memory handle into a
graphics-card-side memory buffer). But we can still do
an SHM copy from pixels->pixmap as long as we only go in
write only direction, via the XShmPutImage API.
