pam_smbpass: REMOVE this PAM module

This pam module causes GPLv3, thread-unsafe Samba code to be directly loaded
into the address space of many system services.  The code in question was not
expected to run in this context, and while using the Samba, rather than the system
password file is a admirable goal, this needs to be done over inter-process
communication, such as is done by pam_winbind.

pam_winbind is not a total replacement, as the migrate functionality used
to keep the Samba password up to date with the system password is not
present, but otherwise can provide essentially the same services.
