Use standard p11-kit module name and location
    
     * p11-kit now wants modules to use <name>.module for module
       config files
     * Put the module config file in the non-admin editable
       location supported by p11-kit 0.16.0 and later.
     * Administrators can still override any setting they want
       by creating an opensc.module file in /etc/pkcs11/modules
       and adding only those settings they wish to change.
