Fixing JitBench (#14364)

- In the lab, the path where the JitBench sources are downloaded is already too long, which eventially causes `dotnet-install.ps1` to fail. Part of the changes are to reduce the PATH where the tests are placed.
- Updated the JitBench version/commit being used. This one is already on 2.1
- Fixing typo on `perf.groovy`
- Increasing the timeout value as JitBench keeps failing on the lab.
