- list-kde: Force kde pattern as well, more complete and still enough space

- list-kde: Force kde_plasma pattern

- Move intel-gpu-tools ignore from list-x11 to list-common (bsc#1125156)
- Install and enable spice-vdagent
- list-kde: Ignore patterns instead of single packages (requires switch to rest_cd_core)
- Enable some -lang packages again

- KDE Live image contains libreoffice-icon-themes for some reason - blocking
to shrink. Remove gcc8 and vim-data from X11 Live image

- Remove netronome firmwares. Somebody using the LiveCD on such specialized
hardware is a stretch. And the firmware for those devices sums
up to > 120MB, which we can make better use of on the Live CD.

- Shrink the KDE Live image a bit: ignore plasma5-desktop-lang and
kate-lang.

- Minimize GNOME live CD: drop zenity-lang and gnome-weather

- list-gnome: buildignore gnome-user-docs and more noto-sans fonts
- live-kde: buildignore vlc-lang and gimp-lang

- buildignore some packages recommended by the base pattern in list-common.sh
