[PATCH v2 2/2] tools/helpers: set event channel for PVH xenstore-stubdom console

[Juergen Gross <jgross@xxxxxxxx>]

In contrast to the PFN of the console ring page the event channel of
the console isn't being set automatically by xc_dom_build_image().

Call xc_hvm_param_set() explicitly for that reason.
