[libvirt] [PATCH] retry poll() in EINTR case in virPipeReadUntilEOF

[Dave Allan <dallan@xxxxxxxxxx>]

I saw a few messages:

libvir: error : internal error poll error: Interrupted system call

during daemon-conf tests.  The messages come from virPipeReadUntilEOF. 
I think the intention is that this case should be retried.  Patch attached.
