[libvirt RFC PATCH] util: vireventglibwatch: watch for G_IO_HUP and G_IO_ERR

[Ján Tomko <jtomko@xxxxxxxxxx>]

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.
