Add support for building Plasma5 on a PAM-ified Slackwarepam

Set the variable SLACKPAM to "yes" in kde/kde.options if you want to
add support for PAM.

These packages will be supplied by a pam-ified Slackware, so they should not
be installed from 'ktown':
deps:ConsoleKit2,cracklib

These packages will react to SLACKPAM variable setting:
plasma:kscreenlocker,plasma-workspace
plasma-extra:sddm-qt5

Uncomment in kde/modules/plasma and compile:
plasma:kwallet-pam
