Installing OpenSusse MicroOS, then installing distrobox, the flatpak-helper
dbus service is not a dependency of distrobox, nor is it recommended. As a
result, the distrobox-host-exec, based on host-spawn, doesn't work, and also
doesn't provide an error message.

distrobox-host-exec is an important feature of distrobox, so it should either
depend on or recommend having flatpak-helper.

Reproducible: Always

Steps to Reproduce:
1.Install MicroOS
2. transactional-update pkg in distrobox; reboot
3. distrobox create -n test
4. distrobox-enter test
5. distrobox-host-exec ls /
6. Notice there is no result.
7. transactional-update pkg in flatpak; reboot
8. distrobox-enter test
9. distrobox-host-exec ls /
10. Now we see the result.

Actual Results:  
distrobox-host-exec doesn't work unless manually installing flatpak.

Expected Results:  
After installing distrobox, I expect the needed dependencies for all features
like distrobox-host-exec to work will be installed.

I think it's quite simple to adjust the dependencies.
