From: Christopher Yeoh <yeohc@au1.ibm.com> 

this patch makes load-oar a bit more tolerant to irrelevant
differences in the oar file format. Directory entries are now ignored
rather than trying to interpret them as files they hold which results
in the load-oar failing. This change makes it easier to manually
modify oar files.
