[ASan] Disable test that sets call stack on Darwin (#170786)

This test fails with the internal shell as we implement ulimit with a
python wrapper. This python wrapper fails on recent versions of MacOS to
set the stack size limit lower, or even to the current values. More
discussion is in python/cpython#78783 towards
the bottom (it seems like a new issue should be opened).

It does not seem like we lose significant test coverage by disabling
this on MacOS as the test running on Linux should catch any major
regressions. We can also simply reenable once the issue is fixed
(although writing a simple c program with calls setrlimit directly also
fails in the smae manner).
