google-compute-config: Reintroduce fetch-ssh-keys
Reintroduce the `fetch-ssh-keys` service so that GCE images that work
with NixOps can once again be built. Also, reformat the code a bit.

The service was removed in 88570538b3,
likely due to a comment saying it should be removed. It was still
needed for images to work with NixOps, however, and probably needed to
be replaced or rewritten rather than removed.

Florian Klink e95d4c734a google-compute-config.nix: use sysctl snippets from gce
We make them available at ${gce}/sysctl.d and add them to
environments.etc, like we do with the systemd ones.

Florian Klink 106a1fe265 google-compute-config: sync with upstream units
With local-fs.target part of sysinit.target
(https://github.com/NixOS/nixpkgs/pull/61321), we don't need to add it
explicitly to certain units anymore, and can change dependencies like
they are in other distros (I picked from Google's official CentOS 7
image here).

Like them, use StandardOutput=journal+console to pipe google-*.service
output to the serial console as well.

Florian Klink 9be0327a49 nixos/systemd: install sysctl snippets
systemd provides two sysctl snippets, 50-coredump.conf and
50-default.conf.

These enable:
 - Loose reverse path filtering
 - Source route filtering
 - `fq_codel` as a packet scheduler (this helps to fight bufferbloat)

This also configures the kernel to pass coredumps to `systemd-coredump`.
These sysctl snippets can be found in `/etc/sysctl.d/50-*.conf`,
and overridden via `boot.kernel.sysctl`
(which will place the parameters in `/etc/sysctl.d/60-nixos.conf`.

Let's start using these, like other distros already do for quite some
time, and remove those duplicate `boot.kernel.sysctl` options we
previously did set.

In the case of rp_filter (which systemd would set to 2 (loose)), make
our overrides to "1" more explicit.

Ding Xiang Fei 359fd5b729 nixos/modules/virtualisation/google-compute-config.nix: pin filesystem type to ext4 for now
Fix #61859.
Assertion fails when a Google Compute Engine image is built, because
now choices of filesystem types are restricted to `f2fs` and `ext` family if
auto-resizing is enabled.
This change will pin the filesystem used on such an image to be `ext4` for now.

Florian Klink 706efadcb6 nixos/modules/virtualisation/google-compute-config.nix: remove google-accounts-daemon
Use googleOsLogin for login instead.
This allows setting users.mutableUsers back to false, and to strip the
security.sudo.extraConfig.

security.sudo.enable is default anyhow, so we can remove that as well.
