KUDU-2422. Fix TSAN hangs in Subprocess::Start
This pulls in an upstream patch from LLVM to fix an occasional hang when
starting processes in TSAN builds[1]
Tested with:
KUDU_ALLOW_SLOW_TESTS=0 ./build-support/dist_test.py loop -n 1000 \
./build/latest/bin/subprocess-test --gtest_filter=\*CurrentDir \
--gtest_repeat=1000 --stress-cpu-threads=3
Without the patch, two of the tasks hung in Subprocess::Start and
failed. With the patch, all succeeded.
