initscripts-shr: add mountdevtmpfs init script for palmpre machine

On the palmpre machine we are currently come into the SHR rootfs through mounting it from
/boot and switch the rootfs via pivot_root. So we can't automatically mount devtmpfs on
/dev. Instead we do this right after SHR begins to boot and before any other filesystem is
mounted on the new rootfs.
