Description of problem:
runtime-install.tmpl has some CJK fonts packages like vlgothic-fonts, naver-nanum-gothic-fonts, and wqy-microhei-fonts though, we want to replace them with google-noto-sans-cjk-ttc-fonts which is default CJK fonts in f29.

Additional info:
runtime-cleanup.tmpl also contains some to drop bold fonts for naver-nanum-gothic-fonts. it should be dropped too. and you may want to do similar for google-noto-sans-cjk-ttc-fonts too to save more space.

For reference, this is the file list in the package:
/etc/fonts/conf.d/66-google-noto-sans-cjk-ttc.conf
/usr/share/fontconfig/conf.avail/66-google-noto-sans-cjk-ttc.conf
/usr/share/fonts/google-noto-cjk
/usr/share/fonts/google-noto-cjk/NotoSansCJK-Black.ttc
/usr/share/fonts/google-noto-cjk/NotoSansCJK-Bold.ttc
/usr/share/fonts/google-noto-cjk/NotoSansCJK-DemiLight.ttc
/usr/share/fonts/google-noto-cjk/NotoSansCJK-Light.ttc
/usr/share/fonts/google-noto-cjk/NotoSansCJK-Medium.ttc
/usr/share/fonts/google-noto-cjk/NotoSansCJK-Regular.ttc
/usr/share/fonts/google-noto-cjk/NotoSansCJK-Thin.ttc

and we maybe need Regular variant only in the installer image?

just for note of the size consumption, 3.4MB will be increased by this change.
