[llvm] [lit] Fix the missing commas in LIT config (PR #162998)

[Kunqiu Chen via llvm-commits]

https://github.com/Camsyn created https://github.com/llvm/llvm-project/pull/162998

This pull request makes a minor fix to the `llvm/utils/lit/lit/llvm/config.py` file. 

The change corrects a missing comma in the list of environment variables, ensuring that `"UBSAN_SYMBOLIZER_PATH"` and `"ASAN_OPTIONS"` are treated as separate entries instead of a single concatenated string.

* Fixed a missing comma between `"UBSAN_SYMBOLIZER_PATH"` and `"ASAN_OPTIONS"` in the environment variable list in `llvm/utils/lit/lit/llvm/config.py`, preventing potential configuration issues.
