elf: Add test case for [BZ #19329] Test concurrent dlopen and pthread_create when the loaded modules have TLS. This triggers dl-tls assertion failures more reliably than the nptl/tst-stack4 test. The dlopened module has 100 DT_NEEDED dependencies with TLS, they were reused from an existing TLS test. The number of created threads during dlopen depends on filesystem speed and hardware, but at most 3 threads are alive at a time to limit resource usage.
