x86/hvm: Bind xen-created event channels to building domain

Instead of using a hardcoded domain 0 as the endpoint for the event
channels created in hvm_vcpu_initialise, use the domain ID of the
building domain so that a domain builder in a domain other than dom0 has
the expected access to the event channels.
