refactor(tvix/store/pathinfosvc/from_addr): use test_case

All we do is constructing some strings, and checking if from_addr
succeeds or not.

This can be written in a much more concise way using test_case.

Use lazy_static to provide temporary directories.

Also add some more grpc-related test cases.
