MALLOC_CHECK: various clean-ups

The most important in this change is to avoid affecting anything
when test-lib is used from perf-lib.  It also limits the effect of
the MALLOC_CHECK only to what is run inside the actual test, and
uses a fixed MALLOC_PERTURB_ in order to avoid hurting repeatability
of the tests.
