hw/s390x/ccw: Replace basename() with g_path_get_basename()
g_path_get_basename() is a portable utility function that has the
advantage of not modifying the string argument, so it should be
preferred over basename().
And also to avoid potential compile breakage with the Musl C library
similar to [1], replace basename() with g_path_get_basename().
