[PATCH v1 23/34] qemuDomainBuildNamespace: Populate inputs from daemon's namespace

[Michal Privoznik]

As mentioned in one of previous commits, populating domain's
namespace from pre-exec() hook is dangerous. This commit moves
population of the namespace with domain inputs into daemon's
namespace.
