Fix install_name_tool calls in OS X "make install".

Unfortunately the changes of r74909 (see #15452) don't seem to have been
tested and broke "make install" completely as libraries were not found in the
"bin" directory where the script was looking for them. Fix it to use "lib"
subdirectory as intended.

Closes #15551.
