[Discuss-gnuradio] Link error in _blocks_swig10.pyd

[Gisle Vanem]

I had trouble linking the _blocks_swig10.pyd block.
(some missing '_imp_' symbols).

So I investigated the ./gr-blocks/lib/ code and noticed
there was a missing 'BLOCKS_API' for the classes in
moving_average_XX_impl.h.t. This patch patch fixed it:
