[libvirt] [PATCH 1/2]: Give /dev/disk/by-{id, path} a chance to exist

This patch is the same idea as my previous patch for giving
/dev/disk/by-{id,path} a chance to exist.  Currently libvirt can race with udev
creation of /dev/disk/by-{id,path}, so if we fail to open the directory, retry
up to 5 seconds.  This is only likely to happen on hosts that are:

1) diskless (so /dev/disk/by-{id,path} doesn't exist already), and
2) slow, and/or heavily loaded (meaning that udev can take some time to create
the /dev nodes).

Based on the feedback from Dan and Jim, I updated the patch to look more like
what is elsewhere in libvirt.
