Make every .bazelrc import the top level .bazelrc (#1644)

Makes the Bazel configuration for every test repository consistent with
the main repository.

Removes `test_version/.bazel{rc,version}`, since `test_version.sh` was
always copying the top level `.bazel{rc,version}` files into the test
repo to begin with. Updates `scripts/sync-bazelversion.sh` such that it
won't replace `test_version/.bazelversion` on future runs.

Also fixes a bug in `test/shell/test_scala_proto_library.sh` whereby it
never successfully read the top level `.bazelversion` file.
