(PA-4871) Add our libdir to the runtime linker search path

When the runtime linker loads executables, it uses a search path in the
executable to find library dependencies. On most platforms this is done
via -rpath, but on AIX it's -R. The search path is embedded in the
executable and can be seen using:

    # dump -H /opt/puppetlabs/puppet/bin/openssl
    ...
                               ***Import File Strings***
    INDEX  PATH                          BASE                MEMBER
    0      /opt/puppetlabs/puppet/lib:/usr/lib:/lib
