GH-102537: Handle check for PYTHONTZPATH failing in zoneinfo test by pganssle · Pull Request #102538 · python/cpython

It is possible but unlikely for the `python_tzpath_context` function to
fail between the start of the `try` block and the point where
`os.environ.get` succeeds, in which case `old_env` will be undefined. In
this case, we want to take no action.

Practically speaking this will really only happen in an error condition
anyway, so it doesn't really matter, but we should probably do it right
anyway.
