Support EXPERIMENTAL_USE_OPENJDK9=false.

This fourth possible value currently has the same semantics
as a default/unset EXPERIMENTAL_USE_OPENJDK9, but allows
people to explicitly switch back to the old semantics when
the default changes.

Test: make showcommands core-oj (in environments with
      EXPERIMENTAL_USE_OPENJDK9 set to "", "1.8", and "true").
