    Unit test fails in pbuilder environment

    When running tests inside a pbuilder environment we don't
    have /dev/disk/by-path directory and so the test_host_driver
    test fails. Fix test by overriding the isdir method to
    return True and pretend that the directory is there.

    Closes-bug: #1244418
