may I please have a review for this tiny fix. 8066474 removed the <arch>
directory from the images and since then -XXaltjvm was slightly broken.
When handling XXaltjvm, os::jvm_path() examines the path of the libjvm.so
to check if it is part of what it considers a standard JDK by traversing a
number of slashes up the path and looking for "/jre/lib". That number of
slashes was off since 8066474.
Note that this only affects cases where the alternate libjvm.so is part of
a full jdk, so it does not affect the gtestLauncher.
Thanks & Regards, Thomas
