Avoid closing unrelated descriptors when spawning fails early#44

VMProcess.nativeSpawn() can fail before calling cpproc_forkAndExec() (null/empty command array, string extraction failure, malloc failure). Since fds[] is not initialized, the cleanup path could end up closing up to three arbitrary live descriptors. Initialize every descriptor to -1 at declaration so all early failure paths are safe.
