Update rules_closure to latest version
Update rules_closure to latest version

The latest version removed Java 7 compatibility mode [1] for
protobuf_java rule.

Note that this above fix is only related to the building protobuf_java
rule itself, and is not related to the building of java_proto_library,
that is also affected, but for another reason: default java toolchain
in currently used java_tools distribution is also targeting Java
language level 7 for proto rules. Luckily my PR was accepted here and
Java 7 compatibility mode was removed. However, to take effect a new
java_tools version must be released and Bazel must be updated to point
to it. This will be done in the follow-up change.
