  Fix ASLR to be smaller during asan/tsan/ubsan runs

Recently asan/tsan/ubsan runs have been failing randomly.  It appears
that a recent runner update may have led to the Address Space Layout
Randomization setting in the linux kernel of ubuntu-latest runner
getting set to too high a value (it defaults to 30).  Such a setting
leads to the possibility that a given application will have memory
mapped to an address space that the sanitizer code typically uses to do
its job.  Lowering this value allows a/t/ubsan to work consistently
again
