[libvirt] [PATCH] add handling EINTR to test example of event loop



From: lvroyce <lvroyce linux vnet ibm com>

some system call and signal will interrupt poll,
making event loop stops and fails to react events and keepalive message
from libvirt.
adding handling EINTR to poll to make it more robust
