[libvirt] [PATCH 02/18] Ensure LD_PRELOAD exists before running test case

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; The linker will ignore LD_PRELOAD libraries which do not exist, just printing a warning message. This is not helpful for the test suite which will be utterly fubar without the preload library present. Add an explicit test for existance of the library to protect against this Signed-off-by: Daniel P.
