Add support of El Capitan 10.11

If the directory /usr/lib/pkcs11 does not exist then try
the directory /usr/local/lib/pkcs11 used on El Capitan 10.11

Because of SIP (System Integrity Protection) introduced in El Capitan
10.11 the directory /usr/lib/pkcs11 cannot be used to install PKCS#11
libraries.  PKCS#11 libraries are now installed in /usr/local/lib/pkcs11.
