tools: support versioned node shared libs on z/OS

The shared libraries will now be stores in lib.target as opposed to
obj.target, libnode.version.so, libnode.x (for npm backwards compat and
testing), and libnode.version.x (for builds). The install will also
include libnode.so link that points to libnode.version.so (this will be
used by native npms for backwards compat).
