libxl: Use cooperative resume for migration

Browse Source 
Migration code specifies the problematic non-cooperative resume mode
which is a known issue with Xen's libxl [1].  Instead, use the better
supported cooperative mode.

Without this, guests BUG() in xen_irq_resume after failing to bind
still-bound event channels.
