added CONFIG_BIGNUM

[neeboo]

To enable BigInt/BigFloat support, we need to added CONFIG_BIGNUM to binary build.

Because qjsc compile code to bytecodes with specific length, with CONFIG_BIGNUM enable, the bytes length is different.

When we use prebuild codes included to WebF or Kraken, especially using javascript polyfill. The code will not be evaluated because ByteCode version is different according to
https://github.com/openwebf/webf/blob/80f32ab9856c7d69ef1ff778e083a323f4f83f51/bridge/third_party/quickjs/src/core/bytecode.c#L2027

Either we should include node-qjsc to WebF and pass different settings before polyfill scripts build. or we should create different binary here.

Just create this pull request to provide you guys to consider. Thanks

I will help to ship a new minor version of node-qjsc.

Maybe this Issue could be fixed.
