[libvirt] [PATCH 2/2] remote: enforce ACL write permission for getting guest time & hostname

[Daniel P. Berrangé]

Getting the guest time and hostname both require use of guest agent
commands. These must not be allowed for read-only users, so the
permissions check must validate "write" permission not "read".

Fixes CVE-2019-3886
