Ensure LD_PRELOAD exists before running test case

Browse Source 
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 existence
of the library to protect against this
