fedora-intune: fix boot issues, add Himmelblau variant
Fixes found by building and inspecting the image:

- Select the Intune authselect profile with-altfiles. Without it system
  users in /usr/lib/passwd (gdm, pipewire, mdatp) do not resolve and the
  login screen never starts. The build now fails if gdm does not resolve.
- Ship /opt as a plain directory (opt-usrlocal: root). Defender installs
  to /opt/microsoft/mdatp and keeps state in /var/opt/microsoft/mdatp;
  with the default /opt -> /var/opt symlink those were the same
  read-only directory. rpm-ostree still relocates /opt content to
  /usr/lib/opt, so finalize.d/60-opt-links links it back (only for images
  where /opt is a directory; fedora-cosmic/remote are unaffected).
- Run Defender's %post on first boot (mdatp-firstboot.service): in a
  compose /var is read-only and the machine GUID/state must not be
  shared. mdatp.service waits for it.

New image fedora-intune-himmelblau: the same workstation with Entra ID
sign-in through Himmelblau (Community Nightly packages), which joins the
device at the first sign-in and enrolls it in Intune (apply_policy)
instead of the Microsoft Intune app. Workstation, Edge and Defender
manifests move to images/shared so both images use them; build.sh copies
images/shared/*.yaml and CI builds both images in one matrix job.

# Microsoft Intune app for Linux (intune-portal) and the Microsoft identity
# broker, from the microsoft-rhel10 repo (shared/repos/microsoft.repo).
#
# Fedora is not a supported Intune distribution. The RHEL 10 builds are used
# because they link against the same library generation as Fedora 44.

packages:

postprocess:
# The intune-portal %post builds an authselect profile with pam_intune.so and
# an SELinux module, but neither reliably survives a compose (no running
# SELinux, authselect state under /etc). Redo both here so the image is
# deterministic either way.
