Fix Bazel 7 build (more) (#35392)

It turned out that the previous change missed two things which this PR
has

- Fix function `_dockerized_genrule` not to have `timeout` and `flaky`
which Bazel doesn't have. (Bazel 7 may either drop these arguments or
become more strict about passing unrecognized ones)
- Disabled python bazel distribution tests with Bazel 7. This needs to
be addressed by https://github.com/grpc/grpc/issues/35391.
