qemu: Map running reason to resume event detail

Browse Source 
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.
