    guestfs: With libguestfs >= v1.41.1 decode returned bytes to string

    libguestfs >= v1.41.1 and commit 0ee02e0117527 changed the return type
    of read_file from string to bytes.

    https://github.com/libguestfs/libguestfs/commit/0ee02e0117527b86a31b2a88a14994ce7f15571f

    As we don't check the version of libguestfs installed this change
    handles both the original behaviour where a string is returned and the
    newer behaviour by decoding any returned bytes to a string.
