    Fix active controller check on backup

    The current backup ansible code is using the raw "system host-show"
    output to grep by "Controller-Active", however, this output is
    formatted in a given way that it is prone to have line breaks.
    As the field containing this info is open to have other infos, and,
    recently, the max_cpu_config was added, this caused a line break in
    the output (the field is the "capabilities").
    Therefore, as this info is not in the database, since it is added
    "on-the-fly" by sysinv, and the system command has the option
    to format the output differently, using: "--column capabilities
    --format value", the current logic can be kept since the output
    comes as a whole string with the field value.

    Test Plan:

    PASS: Perform backup & restore on AIO-SX successfully
