Currently, the installer tests just hang after the initial install phase
on i686 because qemu just quits because of the gic parameter.
Fix this by doing x86 things for both x86-64 and i686.
I needed some other bpf-related tools located in the kernel source tree,
so I hijacked the bpftool package, renamed it to bpftools and added
those programs.
Home-assistant through its `--runner` commandline flag supports sending
exit code 100 when the `homeassistant.restart` service is called.
With `RestartForceExitStatus` we can listen for that specific exit code
and restart the whole systemd unit, providing an actual clean restart
with fresh processes. Additional treat exit code 100 as a successful
termination.
Configures the emulated_hue component and expects CAP_NET_BIND_SERVICE
to be passed in order to be able to bind to 80/tcp.
Also print the systemd security analysis, so we can spot changes more
quickly.
This is what is still exposed, and it should still allow things to work
as usual.

→ Overall exposure level for home-assistant.service: 1.6 OK :-)
This can grow to as much as ~1.9 if you use one of the bluetooth or nmap
trackers or the emulated_hue component, all of which required elevated
permisssions.
git-daemon won't start up if its project directory (here /git) doesn't
exist. If we try to create it using the test harness, then we're racing
whether we manage to connect to the backdoor vs. the startup speed of
git-daemon.
Instead, use systemd-tmpfiles, which is guaranteed(?) to run before
network.target and thus before git-daemon.service starts.
rspamd seems to be consuming more memory now sometimes, causing OOMs in
the test.
Increase the memory given to these VMs to make the tests pass more
reliably.
