util: vireventglibwatch: watch for G_IO_HUP and G_IO_ERR

Browse Source 
To more closely match the previous usage in virEventPollDispatchHandles,
where called the handle callback for any revents returned by poll.

This should fix the virtlogd error on subsequent domain startup:
  error: can't connect to virtlogd: Cannot open log file:
  '/var/log/libvirt/qemu/f28live.log': Device or resource busy
as well as virtlogd spinning caused by virLogHandlerDomainLogFileEvent
never being called on hangup.
