There are no tests, because this is a change in a cmd script only.  I tested manually by launching
YARN daemons in a command prompt where the PATH did not include an explicit reference to the
location of hadoop.dll.  I verified that the daemon loaded the native code successfully.

> ResourceManager and NodeManager do not have the correct setting for java.library.path
when launched on Windows.  This prevents the processes from loading native code from hadoop.dll.
 The native code is required for correct functioning on Windows (not optional), so this ultimately
can cause failures.
