Fix libpng submodule usage 

The current usage used the system `png.h` header instead of the intended
submodule header. This may break if the system header isn't at
`libpng16/png.h`.

Fix the include header to get the genreated include files and the
`png.h` from the submodule as described in
https://github.com/glennrp/libpng/issues/342#issuecomment-864589614
