Remove the directory component from all paths.  This lets libpam search its
default directory for modules, which is needed on multilib systems because
a 64-bit binary can't use the 32-bit modules which are stored in /lib/security.

Use pam_stack to make password-checking mechanisms configurable by authconfig.
