enable windows binary module import

[malyjacob]

enable wondows binary module importing, which allow no modification of the origin scripts using binary module importing in project.

try run on windows:

$ mkdir build
$ cd build
$ cmake .. -DBUILD_EXAMPLES=ON
$ cmake --build . --config Release

And after the above, try copy the target file qjs.exe, fib.dll, point.dll to dir examples and run the following:

$ .\qjs.exe .\test_fib.js
$ .\qjs.exe .\test_point.js

And the output is all right.
