Change default Linux fonts: Latin fonts from Dejavu to Liberation, non-Latin from Dejavu to Noto

[MateusRodCosta]

Fedora recently changed to pretty much replacing their remaining usages of DejaVu with the Noto fonts, not only because of consistency with the other languages already using Noto, as well as the better quality of the Noto fonts. See the change wiki page: https://fedoraproject.org/wiki/Changes/DefaultToNotoFonts .

As well as that, Times New Roman is usually the standard serif font for Web, and the Liberation fonts contains the Liberation Serif font which should be metrically-compatible and look similar enough to Times New Roman.
Also, Liberation fonts are pretty much likely to be pre-installed (or at least pulled in as dependency often enough) on any current Linux distro (could also be made a dependency for the distro package).
