Subject: [PATCH] build: enable glibc's malloc checks for the test suite

Setting MALLOC_CHECK_=3 causes additional checks in glibc for malloc()
usage errors, abort()ing the test if those trigger. MALLOC_PERTURB_=69
causes free()'d memory to be poisoned with 0x45, leading to crashes in
case of use-after-free.
Together, both are useful for spotting more errors during "make check"
