libxc: set all VCPU's online by default in HVM info table

This sets a saner default for the cpu-online-map by setting all bits
to 1. The default assumption ought to be that nr-vcpus ==
nr-vcpus-at-start. If that is not true, then the toolstack must modify
the bitmap, but if it is true, the toolstack oughtn't need to do
anything further.
