Signing of windows executable fails if proxy is required on osx

[johvo]

• Version: "electron-builder": "^19.47.1",

• Target: Build for Windows (on OSX)

• Issue: I'm behind a proxy and it seems the proxy settings are not used while signing with windows executable (when build on a osx machine).
  The used osslsigncode tool has an option "-p my_proxy_url" which seems to be unused by electron-builder.

• Error-message:
