    Fix guestfs.set_backend_settings call

    This method takes a list of strings. It was never failing
    because python-libguestfs takes the input and casts it to
    a list, which turns "force_tcg" into:

      ['f', 'o', 'r', 'c', 'e', '_', 't', 'c', 'g']

    Which is obviously not correct.

    http://libguestfs.org/guestfs.3.html#guestfs_set_backend_settings

    This fixes that issue and leaves a TODO about investigating
    the usage of set_backend_setting for just setting the
    single force_tcg value instead of overrwriting all backend
    settings.

    Credit to Clark Boylan for identifying the issue.
