It is indeed the case that a simple use of vnconfig won't work when
mounting a UDF image that is a file.  However, the man page for
vnconfig(8) gives the hint on what you need to do:

----
           vndconfig vnd0 /tmp/image.udf 2048/1/1/0

     Configures the vnode disk vnd0 for an UDF image to be used with
     mount_udf(8).
----

and if you use vnconfig in the way that the man page suggests, mount_udf
will work as expected.
