Improve CIFuzz tests (#4868) 
1. Fix problem where permissions were being changed to root by non-root test (test was doing this by invoking test_all.py within docker).
2. Mark tests as integration tests so that cifuzz_test.py can be run in a reasonable amount of time.
3. Prevent some unittests from polluting source repo.
4. Add .venv to .gitignore
5. Rename test_test_all.py to the correctly formatted name "test_all_test.py"

OSS-Fuzz: Continuous Fuzzing for Open Source Software

Fuzz testing is a well-known technique for uncovering programming errors in software. Many of these detectable errors, like buffer overflow, can have serious security implications. Google has found thousands of security vulnerabilities and stability bugs by deploying guided in-process fuzzing of Chrome components, and we now want to share that service with the open source community.

In cooperation with the Core Infrastructure Initiative and the OpenSSF, OSS-Fuzz aims to make common open source software more secure and stable by combining modern fuzzing techniques with scalable, distributed execution.

We support the libFuzzer, AFL, and Honggfuzz fuzzing engines in combination with Sanitizers, as well as ClusterFuzz, a distributed fuzzer execution environment and reporting tool.

Currently, OSS-Fuzz supports C/C++, Rust, and Go code. Other languages supported by LLVM may work too. OSS-Fuzz supports fuzzing x86_64 and i386 builds.
