tests/docker: Added docker build support for TSan.
Added a new docker for ubuntu 20.04. This docker has support for Thread Sanitizer including one patch we need in one of the header files. https://github.com/llvm/llvm-project/commit/a72dc86cd This command will build with tsan enabled: make docker-test-tsan-ubuntu2004 V=1 Also added the TSAN suppresion file to disable certain cases of TSAN warnings.
