elf: Update audit tests to not depend on stdout
The tst-audit14, tst-audit15 and tst-audit16 tests all have audit modules that write to stdout; the test reads from stdout to confirm what was written. This assumes the stdout is a file which is not the case when run over ssh. This patch updates the tests to use a post run cmp command to compare the output against and .exp file. This is similar to how many other tests work and it fixes the stdout limitation. Also, this means the test code can be greatly simplified.
