Support passing --force-process-config to node-gyp

[MrAndersen1]

We ran into issues targeting [email protected] which are solved by sending --force-process-config to node-gyp.

"Some old versions of Electron shipped malformed config.gypi in their headers distributions, and you might need to pass --force-process-config to node-gyp to work around configuration errors."

It would be nice if prebuildify supported this in some way.

As a generic solution, we could support rest arguments and forward those as-is to node-gyp, e.g. prebuildify --napi -- --force-process-config. PR welcome, can be done by using opts['--'] of minimist.

Quick reply, thanks. I will probably not make any pull request myself but if anyone else wants to it would be appreciated.
