Fix getting return address in elf/tst-audit28.c.
Starting with commit 1bcfe0f732066ae5336b252295591ebe7e51c301, the test was enhanced and the object for __builtin_return_address (0) is searched with _dl_find_object. Unfortunately on e.g. s390 (31bit), a postprocessing step is needed as the highest bit has to be masked out. This can be done with __builtin_extract_return_addr. Without this postprocessing, _dl_find_object returns with -1 and the content of dlfo is invalid, which may lead to segfaults in basename. Therefore those checks are now only done on success.
