allow /sys/devices/system/node/*/cpumap for newer libnuma

[Christian Ehrhardt ]

Counterpart to https://gitlab.com/libvirt/libvirt/-/issues/515

/sys/devices/system/node/*/cpumap r,

Those changes are usually safe, there is sadly no abstraction for libnuma.
Steps:
1. propose the change as a patch upstream
2. add it to the related Ubuntu releases

This is in qemu 7.2 as reported:

    hostmem: Allow for specifying a ThreadContext for preallocation

$ git tag --contains e6816
v7.2.0

Therefore this is for lunar+mantic

Hi Sergio,
FYI related similar cases (in case you look for reasoning or anything similar):
- https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1989073
- https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1735424

Thanks in advance if you find time, when you submit something to libvirt to address
issue 515, give me a ping. If it is as trivial and straight forward as the similar changes past I might feel empowered enough to merge it there still (I just do not want to be author and merger).

  * Merge with Debian unstable (LP: #2040393, #2037606). Remaining changes:

    - Additional apport package-hook
    - Autostart default bridged network (As upstream does, but not Debian).
      In addition to just enabling it our solution provides:
      + do not autostart if subnet is already taken (e.g. in guests).
      + iterate some alternative subnets before giving up
    - d/p/ubuntu/Allow-libvirt-group-to-access-the-socket.patch: This is
      the group based access to libvirt functions as it was used in Ubuntu
      for quite a long time.
      + d/p/ubuntu/daemon-augeas-fix-expected.patch fix some related tests
        due to the group access change.
      + d/libvirt-daemon-system.postinst: add users in sudo to the libvirt
        group.
    - Update README.Debian with Ubuntu changes

      + d/t/control, d/t/smoke-qemu-session: fixup smoke-qemu-session by making
        vmlinuz available and accessible (Debian bug 848314)
      + d/t/control: fix smoke-qemu-session by ensuring the service will run
        installing libvirt-daemon-system
      + d/t/smoke-lxc: fix smoke-lxc by ignoring potential issues on destroy as
        long as the following undefine succeeds
      + d/t/smoke-lxc: use systemd instead of sysV to restart the service
      + d/t/control, d/t/smoke-lxc: retry service restart and skip test if
        failing; This was flaky on some release/architectures
      + d/t/smoke-lxc: retry check_domain being flaky on arm64
    - dnsmasq related enhancements
      + run dnsmasq as libvirt-dnsmasq (LP 1743718)

      + d/libvirt-daemon-system.postrm: remove libvirt-dnsmasq user and group

      split into logical pieces. File names ...
