Use the rebased forked GNOME Initial Setup

[Kekun]

This overrides GNOME Initial Setup from gnome-build-meta by https://github.com/Kekun/eos-gnome-initial-setup/tree/eos7.0, a fork of https://github.com/endlessm/gnome-initial-setup that rebases its commits from 43.2 to 48.1.

I still need to build and test this.

This fixes #166.

[Kekun]

The branch where I rebased your gnome-initial-patches on 48.1 compares to your 43.2-based one in the following ways:

• Upstreamed commits appear earlier in the tree.
• I dropped all translation updates from Transifex, but kept the commit adding the Transifex configuration.
• I dropped driver: Avoid unused variable with webkit < 2.39.5 as the guarded code doesn't exist anymore.
• I suppressed both GOA-related commits as GNOME Online Accounts has been removed from GNOME Initial Setup.
• I changed the remaining commits so they fit in the new codebase.

Commit account-local: limit full name to 80 characters may be dropped as its commit message suggests it's related to Debian-based systems. Will suggested testing its relevance by dropping it and testing creating a user with a 256-letters username.

I confirm that:

• Endless OS 7 uses useradd, and not adduser like endless OS 6.
• The vanilla GNOME Initial Setup limits full user names to 256 characters (the entry's max0length property is 255).
• That you can successfully create users with 256 characters full names.
• That the "account-local: limit full name to 80 characters" patch can be dropped (hence I will drop it now).

I believe this and https://github.com/Kekun/eos-gnome-initial-setup/tree/eos7.0 are ready for review, let me know what you think of them! 🙂

Thanks! Have a review comment.

I also squashed the fixup commits in @Kekun's gnome-initial-setup eos7.0 branch, then pushed into EOS gnome-initial-setup as branch 166-gnome-initial-setup-48.1. Please update gnome-initial-setup.bst's source, too.

Thanks! Only nitpick. After fix, I think it is good to merge, then let it build and test the image.

Let me know if anything is needed from me to merge this. 🙂
