[scripts/config] Input tolerance for leading space Google fail

Closes: hashbang#16

Post by @ubergeek77 with the details:

> The [Factory Images page](https://developers.google.com/android/images) has some unfortunate inconsistencies with how it is displaying some of the image information.
>
> There are two main issues:
>
>     * Starting with the January 2020 images, Google has been prepending the Build ID field with an unnecessary space.
>
>       * `config` splits that string with a space already, so the index the script expects the build ID to be at will no longer be at that location unless that space is removed before splitting.
>
>     * Google is now serving T-Mobile/Google Fi factory images. They are the last image in each section, so this "TMO/Fi" image will be considered "latest." However, not everyone has a T-Mobile/Google Fi device. If you were to fix the above issue, you'd still have the issue of determining whether or not the user wants a T-Mobile/Fi image or not (I'd imagine you wouldn't in ~80% of cases)
