[libvirt] [PATCH 04/10] ci: Create user's home directory in the container

[Andrea Bolognani]

Some applications expect the user's home directory to be
present on the system and require workarounds when that's not
the case. Creating the home directory along with everything
else is easy enough for us, so let's just do that.
