hotplug: create /var/run/xenstored in xencommons

tmpfs mounted on /run. /var/run is a symlink to that directory.  Create
/var/run/xenstored unconditionally on startup, use -p to ignore errors.

Please ignore this patch, xenstored creates the directory:

tools/xenstore/xenstored_core.c:1811: if (mkdir(xs_daemon_rundir(), 0755)) {
