static-nodes: move creation of static nodes from udevd to tmpfiles
As of kmod v14, it is possible to export the static node information from /lib/modules/`uname -r`/modules.devname in tmpfiles.d(5) format. Use this functionality to let systemd-tmpfilesd create the static device nodes at boot, and drop the functionality from systemd-udevd. As an effect of this we can move from systemd-udevd to systemd-tmpfiles-setup-dev: * the conditional CAP_MKNOD (replaced by checking if /sys is mounted rw) * ordering before local-fs-pre.target (see 89d09e1b5c65a2d97840f682e0932c8bb499f166)
