    Ensure cinder container udev line isn't duplicated

    With the included version of the lxc module in Juno, the udev mount line
    would have 2 spaces on either side of the = sign. While this worked, it
    conflicted with upgrades, which inserted the same line, except with 1
    space on either side of the = sign. Having two lines that were
    functionally equivalent meant that the container cannot restart.

    This patch ensures that the correct line is always present, so that when
    an upgrade happens the udev mount entry is not duplicated.

    Closes-Bug #1497681
