Some apps, such as gnome-builder wants to access data from the
host, for instance in builders case the system includes. If you
have full filesystem access it is not really a loss of security
to also have /ect and /usr access, but for technical reasons
we can't expose them in the normal locations. However, we
can expose them in /run/host, so do that.
