extra file in MIUI

[mmahmoudian]

While trying to package this for Guix, we realized that there is a Google font in the MIUI folder which is not belonging to this project and should not be here:

MIUI/mtzContent/fonts/Roboto-Regular.ttf

I suggest removing it and any other irrelevant file. For now for Guix we are excluding this MIUI folder explicitly during the packaging.

P.s: as a side-note, it would make packagers life much easier it the tags follow the same naming format. You have used v3.3 and 3.4 formats mixed.
