Subject: python: bazel-vendored-inputs: Do not include a copy of the JDK.

* guix-science/packages/python.scm (bazel-vendored-inputs): Delete
links to JDK directories.  Put a placeholder in local_jdk/BUILD.bazel.
(python-jaxlib/wheel)[arguments]: Replace the placeholder for the JDK.
[native-inputs]: Update hash of vendored inputs.
(tensorflow)[arguments]: Replace the placeholder for the JDK; update
hash of vendored inputs.
(python-tensorflow-probability)[arguments]: Replace the placeholder
for the JDK; update hash of vendored inputs.
