deps: updated for KDE 5_17.03

Six packages have been added in order to compile the KDE packages libkface,
digikam and kdenlive:
- dvdauthor
- frei0r
- lensfun
- mlt
- opencv
- vid.stab

Furthermore I (re-)added some sources that I intend to use in the
'testing' branch of ktown. These Slackware originals were slightly modified
and need to be compiled against wayland (also in need of recompilation are
libxkbcommon and qt5 but those sources are already included):
- elogind
- mesa
- xorg-server

+Subject: [PATCH] Fixes to user and session saving
+
+* src/login/logind-dbus.c (method_create_session): No need to save
+  session here, as session_send_create_reply will do it.
+* src/login/logind-session-dbus.c (session_send_create_reply): On the
+  other hand we do need to save the user here, so the file marks them as
+  being active.
