test-lib.sh: Use GLIBC_TUNABLES instead of MALLOC_CHECK_ on glibc >= 2.34
In glibc >= 2.34 MALLOC_CHECK_ and MALLOC_PERTURB_ environment
variables have been replaced by GLIBC_TUNABLES. Also the new
glibc requires that you preload a library called libc_malloc_debug.so
to get these features.
Using the ordinary glibc system variable detect if this is glibc >= 2.34 and
use GLIBC_TUNABLES and the new library.
This patch was inspired by a Richard W.M. Jones ndbkit patch
