Subject: run: Set MALLOC_PERTURB_ to a random value.

MALLOC_PERTURB_ is a glibc feature which causes malloc to wipe memory
before and after it is used, allowing both use-after-free and
uninitialized reads to be detected with relatively little performance
penalty:

Modify the ./run script so that it always sets this.

We were already using MALLOC_PERTURB_ in most tests.  Since ./run is
now setting this, we can remove it from individual Makefiles.  Most
TESTS_ENVIRONMENT will now simply look like this:

  TESTS_ENVIRONMENT = $(top_builddir)/run --test
