[PATCH v6 5/8] tools/xenstored: Use priv_domid for manual nodes and permission

[Jason Andryuk <jason.andryuk@xxxxxxx>]

Usually, priv_domid == dom0_domid == 0, and that is what is expected.
If we rename s/dom0_domid/store_domid/, it seems more likely we want to
actually have the priv_domid as the owner.

That leads to follow on changes to ensure that the priv_domid is created
first.
