Disallow undeclared access to the $(JAVA) and $(JAVABASE) template variables.

If a rule needs these template variables, it will need to declare a dependency on them in the future by adding @bazel_tools//tools/jdk:current_java_runtime to its toolchains= attribute.

RELNOTES[INC]: In order to access the template variables $(JAVA) and $(JAVABASE), @bazel_tools//tools/jdk:current_java_runtime needs to be added to the toolchains= attribute from now on.

RELNOTES: None.
