[PATCH v1 21/34] qemuDomainBuildNamespace: Populate TPM from daemon's namespace

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

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 TPM into daemon's
namespace.
