    linuxbridge UT: Fix a regression of the recent ip_lib change

    A recently merged change, I07d1d297f07857d216649cccf717896574aac301,
    changed IPWrapper.get_devices to use /sys instead of executing ip command.
    Unfortunately it broke linuxbridge unit tests, which seems to assume that
    mocking utils.execute is enough in some places. This commit fixes the
    regression.
