  lvm udev rule fails to call systemd-run

Bug description:
  [Impact]
  Judging from the rule, this probably means that volumes do not disappear when the physical volume disappears.

  [Test case]
  Not available. But since it's just a path fix, it should not be a problem.

  [Regression potential]
  Removal might now actually work correctly, but it's not entirely clear how that could cause a regression.

  [Other info]
  In /lib/udev/rules.d/69-lvm-metad.rules file, it calls /bin/systemd-run command during removal -------
     ACTION!="remove", ENV{LVM_PV_GONE}=="1", RUN+="/bin/systemd-run /sbin/lvm pvscan --cache $major:$minor", GOTO="lvm_end"

  But /bin/systemd-run is not found,  in fact systemd-run is in /usr/bin
  /systemd-run.

  xxxxxxxxxx:~$ cat /etc/issue
  Ubuntu 18.04.2 LTS \n \l

  xxxxxxxxxx:~$ ls /bin/systemd-run
  ls: cannot access '/bin/systemd-run': No such file or directory

  xxxxxxxxxx:~$ ls /usr/bin/systemd-run
  /usr/bin/systemd-run
