Use a JDK version-specific toolchain in `bazel_java_test.sh`
e.g. for ` //src/test/shell/bazel:bazel_java_test_jdk16_toolchain_head`,
this test was previously using `@bazel_tools//tools/jdk:toolchain`, which
was leaking the toolchain from the enclosing version of Bazel. It worked
anyways because turbine was always producing JDK 8 class files, but as of
https://github.com/google/turbine/commit/006a74b6cd7565221a2d7fe9593c103bdd83584c
turbine uses the class file version corresponding to the `-target` or
`--release` flag.
This fixes e.g.
```
java/com/google/sandwich/B.java:3: error: cannot access C
C myObject;
^
bad class file: bazel-out/k8-fastbuild/bin/java/com/google/sandwich/libbottom-hjar.jar(/com/google/sandwich/C.class)
class file has wrong version 59.0, should be 55.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
```
