test: fix require-deps-deprecation for installed deps

Test test-require-deps-deprecation.js was failing when user already had
node installed with acorn in require.resolve range.

Modified test to acknowledge the possibility and throw only if acorn is
found in the deps directory.

Also changed the deprecation test for v9.x: common.expectWarning was failing
because the required deps now throw ReferenceErrors when not properly called
internally in the right order.
