Ever since Dave Zarzycki's patch to sort test start times based on prior
test timing data (https://reviews.llvm.org/D98179) the test suite aborts
with a SIGHUP. I don't believe his patch is to blame, but rather
uncovers an preexisting issue by making test runs more deterministic.
I was able to narrow down the issue to TestSimulatorPlatform.py. The
issue also manifests itself on the standalone bot on GreenDragon [1].
This patch disables the test until we can figure this out.
