udev-extraconf: Use the canonical file name of systemd

The new version of systemd has changed the symbolic link between
/sbin/init and /lib/systemd/systemd to relative. So the output of
the command 'readlink /sbin/init' become:
    ../lib/systemd/systemd

Then it causes the following check of "/lib/systemd/systemd" to return
false. Fix this issue by using the canonical file name of the systemd.
