Craig Small fc97889b2d build-sys: Handle zero length diskstats in tests
vmstat -d testsuite will fail if your /proc/diskstats is present
but zero length. While this seems buggy behaviour from lxcfs, its
there and its a simple matter to test for it and skip those tests
if we are run on a zero length /proc/diskstats system.
