fix running pencil in no-sandbox with --no-sandbox

[simonjoom]

i use pencil in a termux android and apps in there cannot be run sandboxed
running ./node_modules/.bin/electron --no-sandbox ./app
give an error.

I did some research in electron, they did a patch to allow running application in real no sandbox mode,

I reinstalled the latest electron library (npm install electron@latest electron-builder@latest)
I changed just a bit the configuration inside the package.json to allow to pass the breakage and the app run well !

Maybe i suggest to update electron to the most recent

Thks you
