Mozilla doesn't seem to define all Android prefs/set them to their correct values at `all.js`/`geckoview-prefs.js` anymore - which has caused issues for us in the past (ex. with some of the Safe Browsing provider prefs)
So this ensures that we're using their correct/appropriate default values, though values set by Phoenix and values we define at `ironfox.cfg`/`ironfox.js` still take precedence over them
