[libvirt] [PATCH 4/5] qemu: Map running reason to resume event detail

Thanks to the previous commit the RESUME event handler knows what reason should be used when changing the domain state to VIR_DOMAIN_RUNNING, but the emitted VIR_DOMAIN_EVENT_RESUMED event still uses a generic VIR_DOMAIN_EVENT_RESUMED_UNPAUSED detail. Luckily, the event detail can be easily deduced from the running reason, which saves us from having to pass one more value to the handler.
