Niklas Haas 0540b42657 swscale/graph: correctly handle single threaded mode ...

The code was evidently designed at one point in time to support "direct"
execution (not via a thread pool) for num_threads == 1, but this was never
implemented.

As a side benefit, reduces context creation overhead in single threaded
mode (relevant e.g. inside the libswscale self test), due to not needing to
spawn and destroy several thousand worker threads.
