Fix Desugar duplicating path for dumped classes.

When dumpDirectory (jdk.internal.lambda.dumpProxyClasses) is a relative path, Desugar was duplicating that path because it was resolving lambdaClass.getKey() (which contained already the the dumpDirectory path).

Fixed by ensuring dumpDirectory is always an absolute path.
