Add `alwayslink = 1` to fix undefined symbol linker errors for Swift for TensorFlow.
Context: https://github.com/apple/swift/pull/28438#issuecomment-557736052

Related Bazel change: https://github.com/bazelbuild/bazel/issues/7362
(`--incompatible_remove_legacy_whole_archive`)

Previously, libraries were wrapped in `--whole_archive` and `--no_whole_archive`
so that entire libraries were linked. With Bazel 1.0, libraries that export
unused symbols must be explicitly tagged with `alwayslink = 1`.
